Why is it so hard for non-christians to celebrate a holiday without renaming it?

I do believe that the significance of Easter is lost in the pagan rituals associate with it much like Christmas.

I don't celebrate any of those holidays nor did I rename them. You renamed the celebration.  Except in the Germanic language countries the rest of the world calls your Easter a derivative of the Aramaic/Greek word Pascha.

It’s the last day of Pesach to me because I’m Jewish and I couldn’t care less about your holiday which I’m purposely not naming. Jerk!

Pagans celebrate Yuletide with Tinsel and Coloured lights and Ostara with hares and chocolate eggs.

We conform with the dates designated as public holidays; no big deal.

Not one non-Christian I know calls it anything other than Easter Sunday.  My Jewish friends call it Passover, which came before Easter did.  So who is really renaming holidays?

Maybe they felt guilty....

Christians desperately want to be original, so they do whatever they can to obfuscate the fact that every single aspect of their superstitious beliefs is ripped off from other religions.
