Used to be Christians complained about the use of Xmas literally taking the Christ out of Christmas. Then Wikipedia came along to inform them that Xmas is older than Christmas because the X is the Greek letter for Chi which stands for Christ. As old as the 16th Century, ‘y’all.
It was even used in magazine advertising in the 1920s. So have a merry.
Not that there hasn’t been a real war on Christmas, whatever the left says.
