Dh and I are very faithful Christians. That being said, we celebrate Christmas strictly as a secular holiday and not as the birth of Christ. We believe Christ's birth should be celebrated daily and not when "man" decided it should be. But we understand the general population acknowledges it as Christ's birth and it in no way offends us.
I know this post asked about ppl who don't celebrate it, but I just thought I'd throw in what we do.
