No because they aren't owned by the government.
I personally don't care, before anyone snips at me. I'm just stating the logic. Sears isn't owned by my county and they can do whatever they want and plaster the building in "Jesus is the reason for the season" banners for all I care. No one could stop them.
My city puts up both Christmas and Hannukah lights on the lampposts and I think it looks quite nice. It's more representative of the people who live there than just Christmas decorations.
Honestly, I'm getting sick of being mad about people bashing and banning Christian and Jewish stuff. Really, Christmas in America has as much to do with Jesus' birth as fruit cake has to do with fine cuisine. So who cares, it's all about Santa and buying crap for everyone.
----News Alert----
The only good that comes out of celebrating Christmas these days is the great month of billing Visa has in January.
Let 'em kill it, we could just go back to basics and celebrate Christ's birthday without all the merchandise. And the Jews can celebrate hannuka and the muslims can celebrate Ramadan. Maybe it is a good thing in The LORD's eyes that they are taking Christmas out of the public square, we certainly took Christ out of it years ago (I admit I'm as guilty as any of this btw).
You underestimate the power of PC. One of their non-Christian (or maybe even Jehova's Witness) employees could claim that creates a hostile work environment.
