I hear politicians on both sides of the political parties defend the right of Muslims to come to our country. They do so by saying we are a country of immigrants and our morals should allow for these refugees. As for that argument, I say the past immigrants were not terrorists and were not coming from known-terrorist regions of the world as they are today, willing to kill Americans, Christian or not. Times change, morality changes and so should our immigration policies because of a changing world.
