Honestly, it's a bunch of bullshit. Just part of the Pussification of America. I have my own business. I send out Christmas cards to customers. I also make sure they say "Happy Holidays" so I don't unintentionally insult anyone. IMO, it shouldn't be an issue either way. If 26 of 28 office workers celebrate Christmas, let them put up a Christmas tree. The other two can simply smile and nod when someone says "Merry Christmas". Conversely, if those two respond with "I don't believe in that Jesus ****" when wished "Merry Christmas", so be it. No need to get mad. Just tell everyone else so there's no issue with the Jesus-haters.
