It doesnt matter whether or not it says anything about bunnies or eggs in the Bible. It matters that Easter is traditionally a Christian holiday.
I dont care if you call it Easter, or if you dont call it Easter. But have the respect to remember that Easter is originally Christian, and just because you like the part involving chocolate eggs, does not give you the right to be offended when Christians want to still call it Easter.
EDIT: Another thing, how many of our customs, sayings, idioms and other cultural stuff were raided from other cultures? Think about all the food - jerky, barbecue, pastrami, jerk chicken, chicken curry, sushi. Think about calling people Luddites, about calling someone a grammar Nazi. (Edit: my point about this list is that we didnt feel the need to rename all of these things so as not to offend others. Sushi is still sushi)
Think about having your child dress up as a pirate. Do you know what pirates actually did? They raped, looted and plundered their way across the ocean. They were not nice people. Yet you think its "cute" that your kid dresses up as a widdle pirate for Halloween? As a murderer and rapist? That's cute?
When you say that someone is a grammar Nazi, you are saying their grammar standards were as strict as the standards by which the Nazi's decided whether someone went to the gas chambers or not. Not a very nice thing to say, or remind people of.
So, if you want to be offended by Easter and Christmas, why stop there? So much of what you think is a normal part of culture is flipping offensive to someone out there.
