It’s actually kind of, sort of like that! The Christians’ winter holiday is celebrated using various traditions and trappings of a variety of other, earlier established religions, either directly or indirectly appropriated from them and their worshippers’ cultures. 😆 Even the date of Christmas was likely coopted in this fashion under the rule of Emporer Constantine in the 4th century AD.
And, you know what? Meh. Who cares? One, this sort of thing happens. Two, they lost their war over Christmas decades ago… to their own culture.
