Problems around problems like Separation of Church and state like now could kill millions of Americans during next 10 to 20 years

 If Trump is able to stop freedom of Religion (his adherents) then millions of people will likely die in the U.S. over the next 10 to 20 years because of this.

Republicans often think that Democrats don't know how to use guns. However, the problem is that there might be an equal amount of Veterans and trained soldiers of both parties. Many of these people have AR-15s or Kalashnikoff submachine guns at home.

So, people who are Republicans who don't think Democrats are armed are fools. So, interference of the Separation of Church and state in the U.S. would likely kill millions of people under certain conditions, especially among people who don't fit into just protestant or Catholic molds. 

The people in the U.S. likely most against this kind of war would be the Catholics who have already seen millions and millions of people die in Europe from this since the 1500s.

So, people who don't believe in God and who have different beliefs than Protestants and Catholics would be the first to shoot people who tried to take away freedom of Religion and the separation of Church and state like it presently exists in the U.S.

This could be the next civil war in the U.S. just  like in Europe over Freedom of Religion and the separation of church and state.
