Ah, turning into a Cool Hand Luke, I see.<quoted text>
You already answered my question. The only reason government has to be involved in marriage is because of the children and the weaker partner (mother).
If you remove the issue of children, you again raise the question; What prevailing reason does government have in supporting and regulating selective friendships?
You haven't answered my questions.
You continue to deny reality by refusing to submit a valid reason for banning gay people from marriage.
You know that there is no valid reason to do so.
