They’re all competing for the prize, but my bet is on polygamy to be the winner. It’s got the most going for it:
* All the arguments for gay marriage apply to polygamy, which isn’t true in most of the other cases
* There are some pretty solid accepted traditions of polygamy out there, unlike the other perversions. Even in the U.S. we have the historical example of the Mormons.
* Polygamy is more likely to be acceptable to relatively “prudish” people than the other perversions, because it introduces nothing really strange or revolting into the mix in terms of sexual acts.
I would agree but the feminists would put up resistance to the idea calling it exploitation of women. Just a guess on my part and I guess they could surprise me and support it.
