In Saudi Arabia the religious police try as hard as they can to stamp out Christmas. The word can't be mentioned, and even private celebrations have to be done on the sly.
When I was there, a fellow soldier was passing around a cassette tape of Beach Boys Christmas music he'd purchased in town. We were cracking up because the track listings were for the songs "Blue Winter," "I'll Be Home For Winter," etc. I asked "What? Does seeing the word 'Christmas' burn their retinas?"
It was kind of like being in Macy's, only without the hypocrisy of a big "After Christmas" sale.
