Me too. And we sit and celebrate with my atheistic family. Nobody ever talks about religious meaning of it, it's just and occasion for us to spend time together and open gifts.
Until the War to Force Christianity Down the Throats of All Americans started (better known as "the war on christmas") I felt pretty much the same way. But since it's now a point in the minds of many right wing religious zealots to "defend" Christmas, I'm not going to play along. I've been on the fence as far as telling my in-laws that I'm not participating in Christmas activities, but this year I'm not participating in Christmas activities. I don't like it in the first place and it has no meaning for me in the second place.
