I am working on a post about how much I hate this (not this particular post, but the whole discussion), but I got sidetracked by thinking about a particular intersection of sexism and ableism.
I don't think I'm the only person to have witnessed this series of events:
A young woman in a staff role encounters a developmentally disabled guy who "accidentally" touches her breasts, jokes about her being a stripper, jerks off in front of her, etc.
The woman is upset. She talks to a more experienced staff person, or to her supervisor, and is politely told to get over it.
Don't be upset, it's funny. He can't hurt you.
Don't be mad at him, feel sorry for him because he doesn't know any better.
When I talk about this I don't mean to imply that men with developmental disabilities sexually harass women more than other men. I'm also not sure that people's reactions are that different when it comes down to it. The staff/disabled power dynamic is just stacked on top of the idea that men should probably get to do whatever they want, so that both people are getting a shitty consolation prize for not having power.
I mean, what you tell a woman in this situation basically boils down to, "Why not be a good sport and let him have this one thing? At least you're not disabled."
