It’s a Muslim thing...let them do what they what they want to each other. Bomb them if they try to to go outside of their own land with this crap.
Eventually that will be the policy... it'll be like the iron curtain - only in reverse. Islam creates surplus men - men who must be killed off through jihad. It's been that way since the evil religion started and it will be that way until it ends. There's no reason for us to help them in their evil.
