Exactly, why would he "almost want to hate" his three gay friends because of the actions of a forth random asshole?

Gay or straight, what he did was sexual harassment. Granted, your response wasn't right, either.

Actually, going off the time stamps, it is more like 2 or 3 words a second.

as far as your story, it is pretty ridiculous. You werent in the wrong... Exactly, but you rpobably could have been more diplomatic about it.

In 2014 your not allowed to have an opinion these days due to the sensitive nature of society. If you have ever seen the movie "Parental Guidance" they have their kids play baseball with no score because they don't want anyone to feel bad. That's the way the world is moving towards with everyone being so sensitive and restricting peoples opinions to the point where if you go against the grain it's a social media/petition away from being scorned.

The other guy was being mildly annoying, you threatened to rape someone and called him a homophobic slur. The store did the right thing, and I would have done the same.

Going against the grain, you mean like a guy trying to pick up another guy at the liqure store?

 It happens.. You shouldn't WINE that much about it....... Leaving jokes aside,  the french bottle part made me chuckle... It wasn't the nicest way you could have responded to him, but it  was still kinda funny..

Because saying "Sorry, I'm not interested." is such a hard thing to do...

I don't really understand. You must have known when you threatened someone else, even if it was conditionally, that you'd be asked to leave? If you don't regret it, that's fine, but there isn't much validation to be had beyond that. Though I don't blame you for being annoyed at being touched, you handled the whole situation poorly.

Exactualy, op provoked the situation by being snarky and "clever", after that he had no high ground.
