No. I don't think that polygamy is acceptable anywhere, in our modern world. It is degrading to women, brain-washing, and destructive to families. Just look at the fundamentalist Mormons in Utah who do practice polygamy... from this they start to think rape is OK, they begin to think that 50 year old men having sex with 14 year old girls is OK, and many other disturbing things. In short, I think that it's a terrible thing and there's a reason why this was stopped in most parts of the world a long time ago.
