I agree that wahabi preaching mosques should be closed. I have been to Saudi Arabia and have seen how poisonous that ideology is. 

I think you would agree that neo-Nazi organizations should be shut down. That ideology caused over 60 million deaths in Europe. We should not accept those people under the guise of diversity either. 

Communist/Socialist parties across the world should also be shut down. They have caused over 50 million deaths in USSR, China, Cambodia, etc.
