Exactly, pdq. I mean, heck, I don't have any problem ignoring Chanukah or Purim, and they don't bother me at all, so why should a Jew be bothered by Christmas when he can just ignore it?

Just focus on what works for you. I've never been to a Bar Mitzvah and I didn't even notice what I missed. Nor have I ever been baptized. And I haven't been to Mecca. Yet...somehow I feel reasonably fulfilled in any case.
