Just a small point, but the number of radicalised British Citizens with roots in Pakistan (mainly, but there are others) makes all British Citizens legitimate targets for those fighting a war against Muslim-inspired terrorism. Sometimes when I arrive at Terminal 3 and join the queue for British Citizens, I could swear I'm in the wrong queue, or the wrong Country even.
Don't get me wrong, I'm all for multi-culturalism, I live in the rainbow Nation after all, but there are very sound reasons why the information-gathering anti-terrorism spooks around the world are very interested in what goes on in the UK. That isn't going to change.
If you don't like what your Government is doing, vote for another one. If you can't, then accept that you're in the minority.
