This should come as no surprise. Every few hundred years, some group of progressives wages war on a December holiday.
For example, back in the sixth century A.D, the pagans of northern Europe were finding that their holiday traditions were under attack from the Catholic church. Instead of their traditional Yuletide activities like sacrificing pigs to the god of fertility and conjuring the spirits of the dead, they were forced by the damn papist PC police to observe the birth of Jesus.
Look, Rome. Christianity's popularity in Italy didn't mean that it had to be adopted everywhere. Paganism didn't need to be put to some kind of "global test."
