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.
no. Marriage is not a religious institution, and no church should or would ever be forced to conduct same-sex weddings if such unions violate their beliefs. However, it is immoral to force your religious beliefs on people who do not share them.
