That's not the point. Yes they are evil, I'd go as far as to argue that anyone who calls for the death of a group of people based on something they were born into are evil. The point is that when the precedent or ability is created to do these sort of extrajudicial actions to evil people, the ability still remains for it to be used on non evil people. If you let powerful people silence others based on how much you disagree with them, you will quickly find out that there are groups you think are ok that others also think should be silenced
