Seriously. Of all the men I’ve met in my life I could count on my fingers the ones that were actually half as terrible as the Internet likes to pretend all men are.
Like most men are ignorant about how to treat women but they aren’t sexist. If you explain to them what to do without being mean they’ll understand.
BOYS can be sexist, but so are girls and that’s different because children are just all around immature.
In fact I think tumblr is basing its view on grown men on the behaviour of middle school boys. That can be the only explanation for why they see men the way they do.
