He admits that he is conflicted about the whole gay marriage and adoption rights which to me says he probably wouldn't be acting against it but he also won't be acting for it.

There are many reasons why someone can feel conflicted about something such as gay marriage and adopting but probably is linked most with upbringing and whether or not religion plays a factor. I'm guessing that he is personally conflicted rather than logically.

But from what I have heard adoption is a hard enough process without being gay.
