How do you spot a Christian? It's simple: they're the ones who love everybody, forgive their enemies, never judge others, and treat small children with respect.
That's how it's supposed to be anyway; that's what Christ said his followers should do, and if the New Testament can be relied on, he never said "Thou shalt wear a silver cross visible at all times".
What's more, if I remember right, the airline had a blanket ban on staff wearing jewellery, and far from suffering discrimination, Nadia Eweida was asking for an exception to be made for her.
I think the Court of Human Rights has made a fool of itself; what do others think?
