Ah, okay, so it's not laughable or inarguable, you just don't agree with it. Fair enough.
I don't either, I just don't consider it laughable or inarguable (and let it be noted, to those who didn't check it out, that in the link he does actually supply material from the text, including the earlier version, that he uses to support his reading) or dismissible (classing it as some therapeutic healing experiment, or whatever reductive frame you want to use - how dare he have a personal reason for looking at the text differently and admit to it upfront!).
In fact, I'm sure he'd agree that it's about ethics - of course FRANKENSTEIN is about science going too far, there's no denying it. It's just that it can ALSO be about a lot of other interesting things. Absolutes and interpretation don't mix (neither do absolutes and creativity). Mary Shelly didn;t write in a vacuum and FRANKENSTEIN can't be read in a vacuum. I don't get the feeling that he's saying it can ONLY be a gay love story, he's just saying it can also be read as a gay love story. And he backs it up.
Now, how's about a little economic reading of the THE WIZARD OF OZ as critique/support of the gold standard (OZ = oz. = ounce) or a rip-roaring gender discussion on why the boy Tip reclaims his feminine body as Ozma in THE MARVELOUS LAND OF OZ?
