^ Yea, okay. I'm just ASSuming here, but something tells me that illmatic would do just fine in the boys locker room as long as he thinks the half-naked guys around him are straight. If he doesn't want to go, then he doesn't want to go - but it's all about homosexuality.
I think you should try it though ill, if your only reason for not going is being uncomfortable. Only way to get passed it is to give it a shot (A CUMSHOT TO THE FACE BITCH). It's not like you have to dance, you can just sit at the bar with a bored look on your face.
I think your friend is wrong for taking offense to you not wanting to go there but like Casey pointed out, it might be because he thinks you're not really okay with homosexuality. You can either try to explain it to him or dance the night away.
