Polygamy has much more going for it than homosexual marriage - it is natural, it is scriptural, and in certain societies such as ours, where more women want husbands than men want wives, it is logical.
But more to the point: Every single legal argument, every court decision, which has enabled same-sex couples to marry applies with MUCH greater force to legal polygamy.
If the Supreme Court hears the right case, it will be legal, and very soon.
Wait until NAMBLA forces the lowering of consent. Then you will see homosexuals having group marriages with 6 year old boys.
This is what the homosexuals want more than anything.
I don't know why you guys think that group marriage is going to be limited to hetrosexuals.
