'pray tell'...
"..makes a group of sweaty men take their shirts off in the middle of the dance floor start massaging each other""
i have seen shirtless sweaty men of all sexual orientations at all kinds of shows. i've also seen a lot of sweaty women of all sexual orientations at all kinds of shows [much less of them were shirtless, admittedly]. so i don't think it's just the 'homos' that are participating [and i'm pretty sure that this is an effect of a certain drug...].
"...sometimes followed by full on gay orgies on the dancefloor/washroom"
now THIS... this is interesting. personally i have to say, of all the sweaty shows i've been to i haven't seen a gay orgy on a dancefloor or in a washroom. but i'll take your word for it that it happens, and frequently.
so, it's the trance music that makes them do this? and it only affects the gay people in the crowd? because i'm sure i have seen hetero couples doing everything but [again, not orgies, i admit]. so could we also call it hetero-trance? or hetero-music? or people on drugs getting it on?
added: all this to say, simply, maybe we can all choose our words carefully, myself included.
i hear comments like this so often, and despite the fact that maybe 'your gay friend doesn't care if you say it', or it's supposed to be funny and i shouldn't take it so seriously... there are lots of people out there who are hurt by it. that's all.
