What you say is correct in a normal world, but today, there is too much importance put on PC/Human Rights rather than common sense. In point of fact, common sense has now gone completely out of the window.
This was bound to happen. The real problem is how many others have done exactly the same thing in an attempt to get away from a country that has been good/stupid enough to allow such people in in the first place and paid substantial sums in "benefits" to them?!
