I think there is a rumor that Trump if not for gay marriage does anyone remember him ever showing he is for ag?

Is there anything in his past that shows he is for or against gay marriage? or gay people? When he was mad a Rosie O'Donnel he did say her wife deserved better or something like that. I just read in the politics section here that he is against gay marriage. I can't believe he said that. He is open to people doing whatever they want as individuals. He has had 3 divorces in the past 10 years so why would he want to tell others about marriage?
