In Luton (the axis of Jihad) town centre is a square called St George's Square. It's still called that. Every year we have Christmas lights in the town - still called Christmas lights. We also have Eid celerations. And Diwali for the Hindu population. And Easter and Lent. There is room and nobody is offended. I can't speak for the authorities at Munich Airport but if anybody complained about the term "Christmas", on whatever grounds, I think that perhaps they should have been sent a polite letter. By the way, Muslims do tend to understand that there are other religions, with whom they often share a common ancestory or theme (even though they may disagree on some details)
