Trump's Banning of Muslims

Donald Trump, in my opinion, has been a complete joke from when he first announced he was running for President. From his remarks about Mexican immigrants being rapists and murders to his most recent announcement of banning Muslims from entering the borders of the United States has caused tons of controversy from the citizens of this country. What I don't understand is how he continues to have supporters despite his outrageous racial remarks, but I have seen that most of those supporters are racists themselves by the comments they add on videos on Facebook. I personally don't think banning an entire race/religious group from entering the United States will solve much, since that would be going against the First Amendment stated in the Constitution (the peoples freedom of religion). I think it is very discriminatory considering the fact that just because a group of terrorists claims themselves to a certain religion someone like Trump thinks its okay to ban the entire culture from the U.S.  I feel like he completely disregards that mass shootings, in the past, have been committed by none other than white Americans. I really hope that the citizens of the U.S realize how pathetic this man is and don't make him our President. Even Republicans like Paul Ryan can't back up his statement of banning Muslims from the U.S.
