So we should ban all people who have same thoughts with somebody shooting people? OK, we've just banned: Muslims, Christians, Hindus, Jews, Buddhists, Atheists, Communists, Anti-Communists, Socialists, Libertarians, Maoists, Trotskyists, Marxists, Environmentalists, Bernie bros, Republicans, Democrats, Independents... Pretty much everybody. Except for you of course.
