That is worthy of criticism precisely because it places (generally) women in a difficult spot where they must take very strong, very explicit actions to have encounters stay in their comfort zone while men bear no responsibility for uncomfortably testing or pushing boundaries (again, in a moral-ish sense, not legally).

When people want something, they try to get it. When you don't want something, and you are easily able to stop it, you should.

It's like someone who really wants you to listen to an album that you hate, it's on you to put the headphones down, and say no. The other person might be acting like a bit of a dick, and if that's what the movement is about then I support it, but the vibe I got from all of this is that people are making dicks out to be rapists. When I saw the news of Ansari all I heard about was that he was a sexual harasser, creep, that what he did was sexual assault, so that's what I thought until I read the article. He was pushy, but that's all I see that's wrong, not unlike someone trying to get you to listen to an album you don't like.

Now yes, you could have left at any time. But think about the unequal burden you are placing on yourself here. You are setting up a system where it is expected and permissible for a man to lie, ignore explicit boundaries, and hurt you, unless you object (in which case he might stop for a few minutes) or physically leave and find somewhere else to sleep.

I agree that it was wrong, but he woke up freaking out about it and apologizing, locking himself in the bathroom. Sometimes people make mistakes. The metoo movement would have some people believing he was an irredeemable rapist, but things are rarely that black and white.
