I don't think that's what he's saying. People can be raped while drunk, yes. For example, a sober person could put something in someone's drink to make them drunk so they can rape them. However, what Wigglz is saying is that it's hard to tell whether it was rape or normal sex, because drunk people don't think right. In that case, I have to agree with him, and, in my opinion, I don't think drunk people should be allowed to have sex at all for that reason. Even if they gave consent, when they're sober again and happen to remember it, they could think of it as rape.
