I dont find variant to be a bad term. I see "deviant" as relating to natural sexual orientations offensive.

BUT, the "slippery slope" argument is a bad argument because we have laws based on some religious (moral) codes, but not on others.

During the civil rights movement people said that allowing black people to marry white people was the first step in allowing people to marry their dogs, etc. After all, marrying outside your race is against the same good book that says that you should not sleep with your sister. Nothing like that ever happened. Giving two loving people, whether white black, male or female the ability to marry does not mean that we will allow people to marry within their family or outside our species. That is just false.
