That's right. I agree with you there.
You are not going to get me to say that I find meaning or exceptional joy on December 25th. It is a normal day for me, unless it is Shabbat. Then it is more important.
I don't believe that I have ever suggested that you say something you clearly do not believe.
I don't believe that I have ever suggested that you find meaning or exceptional joy on December 25th.
I did note, perhaps mistakenly, that you appear to find December 25th (except those that happen to fall on Saturdays) to be a bit -- depressing is the word that comes to my mind, but perhaps I overstate your own feelings.
I would never presume to suggest HOW you spend December 25th.
But I still insist that I can wish you a Merry Christmas (or a Happy Veteran's Day or a Happy February 4th, for that matter) without that greeting -- in and of itself -- being offensive.
My wishing you "Merry Christmas" does NOT require you to believe in the divinity of Jesus. Nor does it require you to acknowledge the Apostles' Creed.
It merely wishes you happiness on a particular day of the year. And, for many of us, if we wish people joy and happiness on no other day of the year, Christmas is the ONE day we decide to do so.
