Yes, my University has an area just for Muslims and one just for homosexuals. The Christians, Hindus, Buddhists, etc etc, however dont get their own area.
Take from that what you will.
A Muslim will raise a bigger stink about it than a Hindu will. Also, these religions don't really have rules so stringent about praying. Sure, Sundays, go to Church. Nothing for Hindus, I can attest for that.
NAACP is legal. The Klan, is not. The Klan, sure, spreads hate, but if a group of Whites got together to end discrimination against Whites (and there
is discrimination against Whites), then they'll have to watch every letter they say lest it be twisted to be racist.
Fear of being labeled a racist is probably why most of these rules exist. Being pugnacious group further worsen the situation.
