As an Agnostic (and in consequence atheist) I'm slightly enraged that other atheists try to sell Easter as a pagan festival. Easter, together with Good Friday, Ascension and Pentecost are genuinely Christian Holy Days. (Everything else is appropriated from pagans.) The date for Easter is in the bible (and follows the Jewish calendar not the Roman like e.g. Christmas). Learn about what you are criticising.
And the eggs and bunnies? They come from the pagan Eostre. Yep, and they have been appropriated but Easter was there before. And I haven't seen eggs and bunnies in Churches or pastors speak about them. It's more like a folk tradition that the Church couldn't eradicate than a conscious appropriation by the Christian church.
I'm an agnostic atheist, and I'm there with you.
