Merry Christmas

For some odd reason, Merry Christmas vs. Happy Holidays has been a big topic in the news recently.
Why all the fuss when both terms have their value during the time between Thanksgiving and New Years.
Let's all study this together, children.
On Thanksgiving day, you say, "Happy Thanksgiving."
On Christmas day, you say, "Merry Christmas."
On New Years day, you say, "Happy New Year."
At all other times between Thanksgiving and New Years, you say, "Happy Holidays."
Or, if you a tired of all this nonsense, grunt, groan and say, "Bah humbug!"
