I can't speak for everyone but I will point out that the cultural atmosphere is different in different places. I noticed, with a certain degree of pleasure, earlier this week, during President Obama's press conference, that when a reporter started with "Merry Christmas", he responded "Merry Christmas". And when a reporter started with "Happy Holidays", he responded "Happy Holidays". Which I think wasn't random. I think it was acknowledging that different people have different needs or choices or emphasis.
I'm sorry that your community was apprently severely affected by this kind of accommodation to the needs of (probably) minority pressure.
However, for many years, certainly when I was growing up,
it was ASSUMED, in general, by the entire community,
that EVERYBODY celebrated Christmas,
that EVERYBODY went to church.
This was kind of difficult for kids who didn't celebrate Christmas
and/or who didn't go to church.
Some of the pressure nowadays is the pendulum swing
away from those days. A more comfortable accommodation,
the center of the pendulum swing, may happen in your lifetime.
I don't think it's "political correctness".
(First time I've ever disagreed with Page, BTW.)
I think the people who push for LESS Christmas in the general secular community are not OFFENDED by Christmas.
I think they are bothered by the apparently widely-yeld assumption
that EVERYBODY celebrates Christmas
Consider, even the people who DO celebrate Christmas
do so in very different ways.
Did you know the settlers in the Plimouth Colony outlawed Christmas celebrations because they didn't want drinking and revelry
on this solemn occasion?
Anyway, I'm sorry that the community situation in your city or town
seems negative to you. But I do hope we (Americans) can continue
to be aware of and considerate of the needs and sensitivities of ALL
the people, not just the (apparently) majority.
