Why? How do gays being able to marry affect heterosexual relationships?
It has nothing to do with that. Marriage is a religious institution between a man and a women, that's the reason, nothing else. Based on other posts which others have seen I have nothing against gay people. I support gay adoption, repealing of "don't ask don't tell" and I support civil unions.
And I hope that JSojourner's post wasn't directed at me.
My religion says that Jedis have to die, and since you want to enforce your religion onto others, you must be open to me enforcing mine onto you.
