Ah... the 'health' figures. Your point never changes.. and my answer to your point will remain the same.... the solution the health issues is to find medical ways to address disease, not to change or repress a section of society that has always been there and always will be there.

I don't remember the details of whatever "slippery slope" discussion you refer to, but I will almost always disagree with that approach....however... I do not see anyone here actually defending striking down bigamy laws. I even noted that those people in Montana have very little chance of winning their case.... there are far too many posts, fences & terraces on the slope to ensure that whatever slipperyness you imagine to present a danger will not be likely.
