I made it quite clear in the thread that the OP quoted, before this debate even began, that I am in favour of same-sex marriage.
However, the topic of this discussion is not
Is kevlaw in favour of same-sex marriage?
It is
Is there a non-bigoted reason to be anti-same-sex marriage?.
I sincerely believe that there are non-bigoted reasons to oppose SSM. No Devil’s Advocacy required. That you don’t agree with these arguments does not make them bigoted.
