LOL, so typical of American socons. The problem isn't the objectification of human beings, no, obviously not: the problem is the possibility that somewhere, somehow, some people might do a sexual act I disapprove of...
So would you support people having sex and then pooping on each other in exchange for cash? That's pretty much what this comes down to.
This is like saying you don't want to legalize homosexual sodomy/being gay because you are afraid of being hit on by gay dudes in the park, in broad daylight, when taking your kid to the playground if it is legalized.
