And by what possible definition does a "habit" refer to a crucifix on a chain? After all, that is what you stated. Please provide us a link to that definition. Oh, and also one which states that a Rekel is a Christian garment. You fail because your own definition does not match what you tried to claim.
I find it hilarious that you think only foreign staff would be the Muslims you are so clearly nervous of in the NHS! Non white, foreign looking chappies are over represented in the NHS, but that does not mean they are not as British as you and I. Mildly racist but pure xenophobe.
If I'm sick and in need of medical care I don't give a flying **** how the doctor is dressed up. All that metter is that he/she's competent.
