But they practice polygamy. I forbid polygamy and I will hunt them down, like some persecutors who hunts down immoral people. If Hmong hates other Hmong people that forbids polygamy, they will be the first one to die. No polygamy!
That's why you make government laws banning polygamy. Not all Muslims practice polygamy. Whether they break religious laws, is up to them, as long as they are not breaking the government laws. It's the government laws that matters when it comes to the laws of a nation.
I don't want this thread to turn into a religious debate but, if going by your way, Christianity should also be outlawed. Christianity practice slavery, cruel and unusual punishment just to name a few. I'm pretty sure other religions are similar. Why not outlaw all religions. If you are for freedom of religion or lack of, then you cannot cherry pick parts from a religion just so you can outlaw that particular religion, but at the same time leave out certain things from another religion just to make it allowable in the country. To me, freedom of religion or lack of, applies to all religions. People should have the freedom to believe in whatever they want as long as they do not break the government laws.
Seperation of religion and state, concerning government laws, to me means, that religion stays out of government laws. And the government stays out of religious laws. An example of this would be the same sex marriage issue. A government official cannot refuse the "legal" marriage between a same sex couple simply because his/her religion forbids it. The government cannot force a religion's refusal of a "ceremonial/religious" marriage of a same sex couple.
ex: the government cannot force a church to perform the ceremony of the marriage it is against that church's belief. This is because the marriage ceremony, whether performed or not, is not a legal marriage in accordance with government laws.
