It is said that approximately 8% of muslims are radicals like this idiot. What is 8% of one billion? There’s only one way to get rid of them and the world won’t like it but it may be the only way. We surely won’t be able to talk them into changing.
The other 92% or whatever it is will side with them if it comes down to it anyway, so you might as well consider it as a solid 1.2 billion block.
