I Just Don't Get It... Christmas and Atheists

What really befuddles me at this time of year are atheists who celebrate Christmas. Well, I guess they're not "really" celebrating Christmas, but they're celebrating something.

Did someone forget to send out the flyer on what Christmas is? I'll give everyone a hint: look at the first 6 letters of Christmas. WHOA!! That spells Christ!! Amazing.

So I don't understand the crowd that celebrates a holiday for the birth of someone whose existence they don't even believe.

This rant could last for days, but I think I've made my point.
