Reality check:
It already has happened with homosexual sex. It is beginning to happen now with pedophilia.
I suggest you start looking for a second job, because you have a lot of money to be paying out.
Reasonable people can and do make seemingly arbitrary distinctions about life and the law all the time with nary a trace of dischordance about it.
Homosexual sodomy is now legal - as it should be. Pedophilia, bestiality, necrophilia or whatever your favorite philia is will not be made legal as a result of the Lawrence decision.
