It's not that they're getting rid of Christmas.. silly conservatives. It's just trying to be all-inclusive, since not everybody celebrates Christmas. That's why I say "happy holidays" unless I know which holidays, exactly, that person will be celebrating. And technically, it is an okay thing to say, even to those that celebrate Christmas, since the holiday season also includes New Years. One hoilday + another holiday = holidays. Hence, Happy Holidays.
And if they called it Christmas Break, that would be misleading. Since, Jewish, Muslim, Pagan, Atheist, Buddhist, etc. children also get time off. And the break is not just for Christmas. It includes Hanukkah, Kwanza, New Years, Yule, and whatever else there is. Like Festivus. wink And it occurs in the winter season. I believe it's aptly named.
