Religions are clouding people's conscience and judgement with discrimination and prejudice against the gays. Homosexuality isn't a new concept at all, apparently Alexander the Great used to be gay and the Romans used to have orgies with the same sex. Religion might not be the only factor that...
That's just a fucking cop out though, ignorance and gullibility should never be accepted as satisfactory. Religious beliefs are holding society back e.g. with the issue of gay marriage, religious nuts keep pointing to the bible and keep saying shit like "God created Adam and Eve not Adam and Steve".
quite a few USYD students also go to UNSW parties like Oktoberfest, the toga party and foundation day
haven't met any UNSW students that go to Usyd parties, in fact I don't even know of any usyd parties (tbh I am a bit of a social hermit though)
