Jim Cole, in today's Marietta [GA] Daily Journal (see below for link to his letter), continues the highly misleading, "fake news" pretense that there has been or is any "war on Christmas" or that there is any need to "save Christmas" from "political correctness" or from secularists' persecution of Christians. Cole is right that the American holiday has pretty much always had both religious and secular aspects, and he's certainly right that any Christian who wants to say "Merry Christmas!" should do so with no fear of offending anyone reasonable.
But he's absurdly wrong in suggesting that President Trump or anyone else has somehow restored good sense or courage on this.
I'm certainly not, as all who know me know, a Christian, and I don't say "Merry Christmas" lest someone think I've converted, but many non-Christians do say it, as it may mean either, "May Christians enjoy their holiday" or "May Americans enjoy the secular aspects." The Christian church adapted (including choosing a date for it) their celebration of what they consider to be Jesus's birth to fit in with the many other, non-Christian, celebrations this time of year. "Happy holidays" should not be offensive to Christians, as it is nearly always intended to be inclusive and not critical.
I certainly take no offense if someone wishes me a "Merry Christmas," unless, as has very occasionally happened, it is issued with a bit of snarl and clearly intended to rebuke me for my atheism.
