There is a massive link between aids and the practice of homosexuality....Even large numbers of homosexuals are now saying this.
I dont have to prove anything, but you have to prove that the link with homosexuality is no greater than any link with practicing heterosexuals.
If you fail to prove your point, this would suggest that homosexuality is a dangerous and unhealthy practice,and "marriage" between homosexuals should not be legalised in the same manner as incestuous "marriage" is not legalised.
