I think the subject of same sex marriage is touchy, maybe too touchy for SE at the time since for one they originate from japan where its not allowed, and they have to think of it from a business perspective, nobody has an issue with straight marriage but there is a big number of people who aren't for same sex marriage.

I believe asking for it at the time is on the same magnitude of asking for polygamous marriage, which is ok in some places and not so accepted in others.
