Why Not?

Just a little sumpin’ to throw into the gay marriage discussion. If gay marriage should by legal why not polygamy and polyandry? Since we are redefining marriage shouldn’t we then allow husbands to have multiple wives or allow wives to have multiple husbands? Why not? Makes about as much sense as two men marrying or two women marrying. Just askin’. I’m waiting to see how long it’s gonna take for a Mormon to bring up polygamy. If being against gays marrying makes one a bigot, doesn’t the same apply to opposing polygamy and polyandry?
