sorry i didnt make the second point clear what i meant was, fair enough you can change immigration laws etc to allow/block anyone based on any criteria
but can a government make a policy to identify and remove the Muslim population that is already here? thats what i meant by there is nothing we can do about it If there is say 1million already, can you remove them? no and there is not a way to stop them having children, of which they do have an above average number of children cant do a thing about it
