It's not society's place to tell anyone they're wrong for being homosexual. When judgement day comes they have to stand before God and account for their life and their decisions and me for mine.
We all just go through life doing the best we can, trying to survive and find a bit of joy along the way. If they find love and acceptance in the arms of the same sex then that is their choice. If they are a emotionally stable couple and can provide a child with a good loving home...who cares if it's two men or two women? As far as marraige for homosexuals go...It's just a title, what's the harm? How is it any diffrent than saying "Civil Union"? If that's what the want to call it let them.
