I think this video from Focus on the Family's Stuart Shepard pretty much sums up the mindset of those who annually fight the "war on Christmas":
It's almost like Shepard is entirely unaware that there are millions of people in America who aren't Christians but who also celebrate holidays this time of year and that advertisers might want to reach them as well.
And considering that Shepard thinks that "the entire nation is ready to celebrate Christmas," that seems to be exactly the case.
