I dont know, it might be because some of them think it looks cool to do that, or some homosexuals just like to make their sexual orientation painfully obvious, maybe to attract other homosexuals? Cause if noone acted effeminate, how would you know who�s straight and who is gay? There should be a section in Dave Chapelle�s show called "Ask a Homo", just like their "Ask a Black dude" section to clear up on any questions were afraid to ask.
My earlier comments were directed towards anyone who doesn�t like -not necessarily hate- homosexuals. "They just disgust me" and "Yes" can be pretty much merged, I think.
