Little Englanders foaming at the mouth about Islam in Britain, you sound like a 75 year old pished guy in a bowler hat and orange sash ranting in the pub about the looming threat of the papacy.
Ordinary Muslims you'd encounter in the UK are no more sinister and alien than ordinary Catholics. One day a week they maybe (or not) go to a fancy building to talk about God in a way that you don't connect with. Please try to be normal about that rather than let it eat your whole identity.
