ReligionForBreakfast points out that linking the Easter Bunny to an alleged Pagan goddess named Eostre falls apart under scrutiny for reasons including that the tradition was way newer than that, "Easter" is just the English word for the holiday, and the fact that the critter in question is not always a rabbit (there are Easter Foxes and Storks, for example). There are many rabbit/hare-related traditions in mythologies around the world, but the Anglo Saxon folk deity was not even one of them outside of Jacob Grimm's basless speculations and then some other Protestants centuries after she would have even been recognized. I do like that he, being a religious studies PhD, also points out that the supposed Christian roots sometimes pointed out, what with the association with the Virgin Mary and rabbits in medieval art, is also likely not the source of the Easter Bunny either because there's quite a leap (like the leaps rabbits make!) from "painting Jesus's mom with bunnies" to "bunnies pass out eggs on this holiday he's associated with."
