About the homosexuals and feminine guys?
I'm not going to say there are no homosexuals and anyway, they do not bother you. They don't. If you don't wish to talk to them, then don't. Its fine.
But many of them are just ... well.. gentle guys... feminine if you will. But they are not gay... and IMO, its okay... nothing wrong...
Anyway, a lot of this stigma/rumors, well, its like everything else... don't tell me no one ever told you stuff about BMT? Many are exaggerated tales, made taller just to scare you.
If you want to develop further as a musician, MDC is a great stepping stone...
