When I lived in Sichuan, Christmas was celebrated in big ways by atheists (and a few others). I always wondered at thin, young Chinese men, dressed as Santa without any padding. They were for the most part commerical, encouraging buying in the local department store. I didn’t take offense as I am not religious, but I wonder if some Westerner, deep into Christ and St. Nick, might take offense. Of course it wasn’t an isssue because, aside from the occasional Tibetan and in univeristy housing, I could go days without seeing anyone who wasn’t Han. Who was there to offend?
