Thats the political stance directly opposed to support.
the answer to both questions is yes - people can have conflicting ideologies.
Being against giving someone (or something) rights is politically equivalent to being against that thing.
If im a proponent of black people not having the right to vote, am i anti black or do i just think people shouldn't vote?
Actually youd have to say, getting rid of marriage for straight people.
And yes, if someone was saying we should get rid of marriage for straight people specifically, they are being anti-straight people; they are in favor of stripping rights away from a specific group of people against their interest.
>the majority of people against gay marriage, religious people, aren't against gays per se, they just want to reserve the right of marriage for straight people.
Right, and jim crow wasnt against blakc people per se - just that white people wanted to preserve their water fountains and deli counters.
However, I don't think the path to get there is by denying rights to other people. It's clearly anit-gay to non-religious folks, but popular teachings of the bible (and the teachings of Jesus) prevent many people from seeing it.
