I found myself saying that a lot over this last month.
Society is slowly shifting towards a viewpoint that not everyone celebrates that holiday. It is not commonplace anymore to say those things.
Thus, I'd like to say that "Merry Christmas" does not offend me, but I hope that when I say that to others, it does not offend them either.
It is the thought that counts.
Many people still celebrate this joyous holiday.
With that said, "celebration" varies differently amongst many people.
Stay safe during the holidays.
