How about if every gay and lesbian in the country just randomly (and legally) married a person of the opposite sex who was willing to do so? How about they do that, reap some tax benefits, and then get (again, legally..) divorced? Then, how about they do that every time it would get them a benefit that unmarried people don't have?
Would that be less costly to taxpayers and less damaging to the "sanctity of marriage"?
Extra bonus points for the ones who marry, adopt a child, and then divorce, with the hetero stating that they don't want custody. MAN that would RULE.
