It's amazing that you can be so willfully ignorant.You are talking as though deporting illegal aliens was illegal. EARTH TO FLOPPER. NOT deporting them is illegal. What is also illegal, is the existence on mosques in America. Closing them is required by law.Trump is not anymore going to close mosques than he's going to deport 11 million people. He can't without the support of congress which he certainly won't get and he would have to get pass the courts which again isn't going to happen.
Frankly, I think he threw out his attack on undocumented immigrants just to test the waters to see if there were enough racists, protectionists, and lunatics out there and sure enough there was. In fact, his attack was so successful at getting support, he decide to go after the American Muslims. I suppose it he's successful here, he'll go after blacks. It makes good political sense because the Democrats are going to get the minority vote anyway so why not turn it to his advantage.
As far as fulfilling his promising, he has a perfect out. Those gutless professional politicians in congress and liberal judges will tie his hands.
I don't know if the mosques will (hopefully) be closed, but Operation Wetback 2 is 14 months away.
PS - to call an illegal alien an "undocumented immigrant" is about equivalent to calling a bank robber an "informal withdrawl agent."
Why do you hate this country and our Constitution?
