Interesting essay. I don't think it was the life-changing experience for me that it was for some, but I can see how it would be. I thought the llama metaphor was milked past dryness, and I thought that it could've explored a bit more beyond using ability and willingness to commit fatal violence as a measure of the sexes, but overall I thought it was plenty worthwhile.
Regarding the stories about being the first one to step forward to help and seeing others follow in your wake, had a couple related associations:
1. One of the Union Dues stories on Escape Pod had a superhero at a Wal-Mart doing a publicity event, something happens that results in an injury (I don't remember exactly what) and the super-strategist is left with an injured person and a crowd of hundreds of gawkers. He cries out for someone to help him and they all just keep gawking and it just gets worse. Someone pointed out in the comment thread that the super-strategist's strategy was flawed--to deal with a crowd like that you pick a person, single them out of the crowd, say something like "Hey, you in the red sweater, get some ice. You, tall dude, help me bandage the wound," etc. Once that was pointed out, i couldn't unsee it, and a super-strategist should've known what a regular forumite knew about strategy of dealing with a crowd.
2. Reminded me of To Kill a Mockingbird where Atticus Finch breaks up the mob but speaking to the individual people in it, making them aware that they're individual people and not just pseudopods of the amoebic mob. (yes that last part was not how Atticus referred to it)
3. From my own personal history, I remember a time when I was maybe 8 maybe 9, out at the store with just my brother (who is 9 years older than me) to pick up some mundane thing on an errand in the winter. Outside, in the parking lot, just ahead of us, someone slipped in the ice badly enough that they ended up flat on their back. I remember being focused on continuing to walk--we didn't know the person, it wasn't our problem--it wasn't that I wished the person ill by any means. I would have thought my brother would do the same--I'd never thought of him as a compassionate person (perhaps because he was enough older than me that there was never much in the way of emotional closeness between us), and wouldn't have thought he'd be compassionate to strangers. But he stopped. He asked the fallen person if they were all right, helped them up from the ground, made sure they were coherent enough to answer some simple questions, some other people who'd been with the person but walking ahead a little ways came back and were being very attentive and only then were we on our way. Thinking back on it, even a short while later, I became less surprised at my brother's behavior and more surprised at my own. Why did I want to keep on walking? It didn't cost us anything to stop except a few seconds of our time and we were in no particular rush other than the usual winter behavior of trying to get somewhere warm. If the person had been badly injured we could've called 911 from the store. If I had been the one to fall I certainly wouldn't have wanted to just be left there to sort it out myself and under most circumstances I would've lived under the golden rule. I don't know exactly why I wanted to keep walking. The best way I can describe how I remember feeling is that I didn't consider that person a part of my personal narrative--that fall was a part of someone else's book and I had my own next chapter ahead of me. Thinking back, that's a terribly cruel way to think, to leave other people to suffer on their own because they don't look like major characters in my narrative. As with any memories, it's possible that it's incredibly flawed in a hundred ways, but for me seeing the way my brother behaved in that situation was a major ethical milestone for me, one which comes to mind pretty much whenever a similar situation happens when I see someone that might need help, and now I try to do as my brother had done and offer what help I can offer. Even if it's not something potentially life threatening and it's something more like a ruptured grocery bag spilling stuff on the ground, to help that person try to gather it all back together again, or something. It occurs to me that I've never told my brother that story--my guess is that for him there was no particular reason to attach permanent importance to that memory and it has probably gone away completely.
On another of the topics, gender roles:
1. When I had to register for the draft for the first time, I found it incredibly unfair that women didn't also have to register for the draft. I don't know what I would've done if I had been drafted. I would be a terrible soldier. I sucked at sports not because I was unathletic or unskilled but because I consistently overthought everything until the moment for action had passed. Add to that that I have never intentionally caused physical harm to anyone in my life and I'm not sure I'd be able to, and I'd be a major liability on a battlefield. I wanted to know why merely being a dude somehow made me more suited for being a soldier than a randomly chosen woman.
2. Left unchecked, my wife is by far the more aggressive of the two of us, at least in private when we're being ourselves--our worst fights tend to be when one or both of those traits run rampant. In public we both tend to go against our nature... perhaps because of societal training or possibly because of our chosen vocations. She's a pharmacist which holds an element of customer service so being too aggressive is something to resist, while I'm an engineer where I am most valuable to my organization if I am more pushy because I will try to resist the organization making decisions that do not mesh with the realities of the engineering.
3. In the company I work for, there is visible misogyny kind of taken for granted that seems to come from the highest parts of the organization. Nothing that is so obvious that I would know how to report it as harassment, just kind of a general environment thing. It's almost always women who clean up the kitchen when someone makes a mess, almost always women who plan the catering for company meetings, things like that. This in an organization that's more than 80% men (I don't think that part is necessarily misogynistic on the company's part but due to us being an engineering company and there aren't a lot of engineers who are women). This includes women in several departments in several different roles and positions. I try to at least clean up the kitchen if I see something that needs cleaning, but anything that requires more time I feel like I'm jeopardizing my job if I'm not focusing on engineering because I always have tight deadlines to deal with. Not really sure if/what I can do about that.
4. Even if you had parents who didn't try to push you into particular gender roles, and even if you're aware of those gender roles, it doesn't always mean it's easy or possible to disregard the rules. Some are so ingrained. My parents were never pushy about those kinds of things. My parents were divorced before any memory I have, but my dad was always part of the picture and he was far from a stereotypical man and he didn't try to make me a stereotype either, he was always very cool with whoever and whatever I wanted to be. But despite that, crying is pretty much impossible for me. I can probably count the number of times I've cried in the last five years on the fingers of one hand. There have been times when I've needed to, to get an emotional release, but it just doesn't happen. When I do cry it's almost always when I'm alone, and if I become aware that someone can see or hear me, it just shuts off like a closed tap--both the waterworks and the emotions that go along with them. I am aware of this block, and I think it would only improve things if I could remove the block, but that self-awareness doesn't make the block go away.
But that brings up an interesting question. Just why is the majority of media slanted. I think it's because of the simplest reason of all. Money. That, and fear. I think most studio execs are perfectly aware that women are more important than commonly portrayed. Their big fear is that most people believe the myth, and they daren't run against that because it would be "unbelievable".
I don't think it's believability that Hollywood is concerned with necessarily, but conformity. I think they and we recognize that many of the tried and true movie tropes don't represent reality, but there is so much momentum. People buy lots of tickets for movies that are Hollywood formulas, which means that producers and movie studios fund more of them, then people buy lots of tickets. Movie studios give us whatever content the most people vote for with their money, but people in general like ruts, they like the familiar, they have no motivation to shift momentum and Hollywood is a powerful echo of that.
