In some notes on my computer, I find this important historical observation, evidently from something published by the famed scholar Dave Berry in 2014:
“In the old days, it was not called the Holiday Season; the Christians called it ‘Christmas’ and went to church; the Jews called it ‘Hanukkah’ and went to synagogue; the atheists went to parties and drank. People passing each other on the street would say ‘Merry Christmas!’ or ‘Happy Hanukkah!’ or (to the atheists) ‘Look out for the wall!'”
