The Syrian Civil War is one of the most complicated conflicts in modern history. I think one of the reasons why most Americans don't have sympathy for Syrian refugees is because they don't realize how sorry of a state that country is now. If you did, you'd understand why Europe can't seem to handle all the people coming in. When your whole country is a war-zone, you'd want to leave too. Now many Republican Governors have said "no" to Syrian refugees even though the Constitution grants states no power when it comes to immigration.
What conservatives don't understand is that terrorists don't need a refugee program to achieve their goals. They don't want people leaving Syria because they want to continue to slaughter them. They're pulling puppet strings on your fear, and you're dancing like a marionette. Ted Cruz and Jeb Bush have said they will allow Christian Syrians to come over, but that kind of suggestion is like spitting on America's freedom of religion. This is a humanitarian crisis on a global scale, we all share this Earth maybe helping one another might be a good idea.
