Sounds quite a lot like you're admitting you can't find ways to convince people that you are correct so you think that anyone who opposes you should be silenced. Not very mature or 'workable' for a society, is it? Doubtless there are people who think that you are too thick or close-minded to come around to their way of thinking, so whose calls for censorship do we listen to?

You see the problem here, I hope?

For the record, I'm perfectly confident that I could win an argument with someone calling for ethnic genocide. If you're not, I suggest you develop your own arguments rather than call for censorship. The average person is more reasonable than you seem to think.
