it is sick that young adults would be drinking and hooking up at a house party

I don't drink, and I was never one for casual/recreational sex...That aside, I don't think it's sick if that's what people want to do. I do however find it irresponsible. Drinking to any excess and sex do not always make good bedfellows (no pun intended). It often leads to regret, not to mention rape and/or allegations of rape, many an unwanted baby has been conceived that way too. It may not always happen but the risk is extremely high. I just feel like it's not a good idea to go to a drinking party to hook up. That's my personal take on it.
