I'm kind of torn on this one.
As long as anyone can marry and have a legally recognized marriage in the 50 states and worldwide, same sex, opposite sex, whatever, I'm fine with it.
I always thought the Government shouldn't be in the "marriage" business anyway.
However, the intent is what bothers me. This is an end run around legalization of same sex marriage which seems to be an inevitability given the case that will be heard in SCOTUS. If it is used to discriminate against same sex couples it's bad, and I hope it gets struck down, or not passed in the first place.
