When I am in a social situation and am uncomfortable, I generally leave rather than try to get the group (who are behaving as a group/mob) to change course. I don't like parties generally, and specifically those where people are acting like asses. The ass-acting people are getting something out of it, and even that offends you. You are thinking on a level apart from them, and it isn't their responsibility to make you comfortable.
The critical element is that you have been offended by (I could say "chosen to take offense at") other peoples' behavior not directed at you. You do not therefore have a right to "correct" them so that you are not offended, but to avoid offense, you can leave, and you may eventually resort to finding new friends.
We cannot control other people's behavior, but we can control how we react to it. To attempt to control their behavior (or to expect them to adopt your unspoken norms of civility) is an evil that has caused our society much pain, and created a judgemental atmosphere that infiltrates much of our lives.
If you're just looking to commiserate, then, yeah, they were acting like asses. They should have that right. Out of such stupidity can come insights (you seem to be having some yourself in reaction), and when people are letting their hair down, I'd just as soon have them let it all the way down. I like to see it unfold, but I acknowledge that sometimes it unfolds into an ass-ugly thing.
