Why do many people get angry if someone says "Happy Holidays"?

I get really annoyed when I hear someone bitching about being told “Happy Holidays”. It’s polite, they need to get over it and realize that not everyone is CHRISTIAN.

I got into a debate with my friend…and she is saying that this is one nation under God and that for some reason “happy holidays” is a way of pushing Jesus out.

What do you think about the whole thing? I mean there’s a lot of Jews here in America…I think it’s reasonable to say “happy holidays” to people since the majority celebrate Christmas. They should say whatever they want . Some people don’t celebrate Christmas, so I think “Happy Holidays” is appropriate.

I’m not Christian, but when people tell me “Merry Christmas!” then I say it back. No offense at all.
