Gently reminder that Christmas is just a replacement of the pagan celebration of the birth of Mithra, the sun-Divinity of the Mithraism religion. This celebration has been replaced by the fake celebration of the birth of Jesus to replace Mithraism by Christianism. At the same time, all temples have been converted to churches for the same reason.
