* we have had continued immigration of Muslims under the diversity lottery since
* almost no real hate crimes / assaults on Muslims
And this is despite the constant stream of arrests of Muslims planning to kill more Americans, people arrested for funding terrorists and trying to join groups like ISIS and Al Shabab. So things for Muslims in the US is incredibly good given that this demographic group has actually committed attacks like 2 Fort Hood shootings, attacks on military recruiters, attempts to blow up buildings, etc.
And look at Trump's proposal - no more Muslim immigration because we can't vet immigrants like the San Bernadino shooters. Their desire to immigrate doesn't trump American's rights to live - AKA, we have the right to say no to more people from a group that is responsible for terrorism around the planet and can't tell which ones would be the ones to kill us or support their sons doing so.
He's not advocating rounding up Muslims as FDR did the Japanese in World War 2. He's not advocating deporting legal Muslim immigrants. Simply stopping the influx for national security. That's not bad - it is common sense.
Compare this to Muslims routinely killing Christians in the Middle East and enslaving the Yazidis, Trump is downright humane.
