Christmas, easter, april fools, Halloween, all have pagan roots, but that makes them no less legitimate catholic holidays. You know they had temples, religious texts, worship, faith and god before Christianity right? Does that invalidate churches, the Bible, worship and faith as well?Hell, the old testament is considered holy scripture (the Tanakh) in Judaism, and the new testament is considered holy scripture by Islam (as the teachings of the prophet Jesus), does it invalidate the entire religion?There are historical reasons why these holidays were co opted, mostly having to do with helping to sell catholicism to the masses, but that does not void the holidays themselves. The Nazis merely tried to do the same, IE to co opt Christmas as their own, the better to sell their philosophy to the masses (EDIT: this does not excuse the practice of course, and I had similar thoughts about the soviets removing Santa Claus from their culture to replace them with, umm, Father frost I believe. But in all honesty the Nazis have done many things much worse than trying to tie Nazi symbols to Christmas).Note that expert has ever contested the pagan origins of the Christmas holiday, a holiday held on or near the winter solstice (why it moved from dec 21st to 25th i'm not sure, perhaps Wikipedia can help) so if confirmation is that important to you, here it is. Yule was, I think, a festival meant to stop the shortening of the days and implore the sun to return. Could be mistaken there...
