You're assuming that Christmas is celebrating by 98% of all people in this Country. I think you're wrong. But I truly, don't care. Like I said, I love Christmas. I love everything about Christmas and I don't understand why other religions make such a fuss about it.
OK, 85-90%. It's still a lot, and the wishes of this overwhelming majority ought not to be dictated to by the other 10-15%.
Sure the Constitution says: The Congress shall make no law regarding the establishment of a religion..." but what does that have to do with the decision of the XYZ Company to have a Holiday party instead of a Christmas party? "Christmas" morphed to "Holiday" because of active, relentless pressure from the 10-15% who are not content for the majority to let their culture imbue society.
