The fact that business engage in Christmas celebrations instead of, say, Ramadan, is itself a political decision - it places value on Christmas over the celebrations of other religions.

I'm not saying there shouldn't be Christmas events in games - quite contrary, I think having as many events from as many cultures would be a smart business decision and it would make a larger number of players happy. But the fact is it would be a double standard to be fine with that and not with Pride.
