And there is really nothing you can do to get rid of them all either. Unless you kill everyone who believes in the same thing - which is impossible because you don't know what people believe in - there is no way to defeat them. You cannot really defeat an idea. You can only make "them" uncomfortable to the point where all of them will want to stop and change their ways.
