I'm so torn here. On one hand I find selfrighteous reformed -anything- tedious ("disposable sex toys? Is it the 1950s again?). I know people who go to the circuit parties in NYC, some of them take E to dance, and they are good, happy, productive, successful people. They came into it with their eyes open, they paid attention, have good instincts, and everything is fine. They are in no way losers. And they even sometime have mindless selx.
On the other hand I know people who didn't have good instincts, fell in with bad people, took too many drugs, ended up junkies. But you don't have to go to a dance party for that.
I think, though, that if you don't like dancing then you very probably won't have a good time. And it's true you will be in a group of fucked up people, some of them just happy, some of them complete staggering messes. My experience doing that completely sober was not fun. I was totally disconnected, out of sync. And I like to dance.
You're all booked and you seem serious so go, watch, and you never know. I would say the important thing to remember is that if you're not having fun then it's probably not because you're a dork, it's because it's not a scene you enjoy. No need to tear it down, it's just a fact. I would say that you should find other things you might enjoy doing if you really aren't having a good time and want to leave so that you have other options.
