and here we observe that no other religion or race sees religion and government as separate things. They want religion in their laws. So if we allow other races in our country they will vote their religion into our laws. The only way to counter that is white nationalism, or to have an intentional built in cultural leader into our gov structure. Like Japan has a emperor, Britain has a king, etc or a national religion. If we don't have anything people will assume that law is their only moral compass, so if it isn't legal it's 100% A ok. Leaving room for degeneracy and lack of shame for any weird behavior anyone can think of.
The US Constitution is supposed to be a bulwark against such incursions into our way of life. Sadly, it relies on men to implement, and men are quite often corrupt. Having a King like Britain's Charles is no better than having no king at all.
