When in a discussion about homo marriage with someone promoting or in favour of this idea, I have been known to say "Can you inform me with absolutely assuredness that anal sex has the same legitimacy as a healthy form of sexual activity as vaginal sex between a man and a woman?" The discussion usually ends right there.
