"Happy Holidays" v. "Merry Christmas"

Has anyone else noticed the inordinate amount of (sometimes subtle) argument against using "Happy Holidays" instead of "Merry Christmas"? This year I've noticed it a lot more than in the past. And, have even noticed people saying "Happy Holidays" moreso than before. Very intriguing, I think.

Personally, I don't mind "Merry Christmas", "Happy Hannukah", "Joyous Quanza" (or whatever), or any other holiday greeting that people want to use. As long as it's not a Government entity endorsing one of those, of course. [img]/images/graemlins/smile.gif[/img]

Thoughts? Have you noticed this (perhaps subtle) argument going on about the holiday greeting?
