The main reason I think this is because the sexism was too blatant. In our real world, you can no longer get away with cat calls (wolf whistles if you want to avoid cat puns) or hitting on your subordinates, so sexism is more subtle. Women are judged harshly on the basis of what they wear, the tone of their voice, and the words they use. And they are judged on these things in ways that men are not. That's the subtle sexism of today.
It's actually both/and. Street harassment, I'm sad to say, is alive and well. So is workplace sexual harassment, both direct and indirect (although it varies by industry and workplace). I'm a little surprised to hear anyone suggest otherwise, but I understand these things are often invisible to male-presenting people, as catcallers and sexual harassers almost universally save their behavior for when women are alone, or only with other women.
Hell, just today a friend of mine went for a run, and some strange dude decided to join her, harassing her and keeping up creep-banter
for literal miles. That ain't subtle harassment by any standard, and that's in full daylight in a suburban neighborhood in the middle of the day.
