That deceitful unsolicited junkmail deserved ridiculing, but I think he missed an important point. It claimed to be about the true meaning of Easter, but that was clearly a lie. It was Christian and the true meaning of Easter has nothing to do with Christianity. It was a fertility festival worshipping the god Easter (Oestre, etc - pick any spelling you like, they didn't care in those days). Hence the fertility symbols. Eggs for female fertility (Easter was female) and rabbits for fertility in general.
