Realistically, how? There are several million muslims alone in the UK, many of them second or third generation and no longer citizens of their countries of origin. What country will take them? Are we going to charter hundreds of thousands of deportation flights, or load them onto barges, or march them across the continent on foot?
This is going to end in pogroms if the government don't get on board, or sending people to camps if they do. It's unfortunate but I can't see a future where neither of those things happen, the problem has been allowed to get too bad.
