If the travel ban against six Muslim countries is so important to our safety why isn't Saudi Arabia on the list? I believe all but one of the 911 terrorists were from that country! Saudis aren't on the list because they own a big piece of Trump, Inc., and of course their oil. Oil always trumps safety, no pun intended. 
Racial profiling will not work to make us any safer and anyone who says so is a liar! Terrorist organizations are not so stupid as to keep sending young Arab looking Muslim men to do their bidding. They are quite capable of recruiting the blonde and blue-eyed or any other willing body that does not fit the profile. And, the last stat I saw said 78% of terrorist attacks, successful or not were planned and/or committed by American citizens. Trying to pin all terrorist attacks on one group or race is a recipe for disaster. It creates a condition called tunnel vision which means an obvious threat could be ignored because it doesn't fit the profile. Think outside the box!
