Christmas is not a dirty word
Contrary to what the ACLU and several school districts and employers (ahem Macy's!) around the country would like us to believe, Christmas is not a dirty word. Merry Christmas is a perfectly acceptable greeting. Millions of people around the world celebrate Christmas on December 25th, either in a religious context or a context of giving and family. So why the objection to the greeting Merry Christmas?
The ACLU is backwards. Religion is not pornography. And it's not even all religion they're trying to put beneath pornography. It's Christianity and Christian holidays. Schools are free to put on programs about Hannukah and Ramadan and Kwaanza and nary a word from anyone. But sing a song about Jesus's birth or mention God and you'd think the sky was falling!
The ACLU fought the passage of the Children's Internet Protection Act, which was meant to protect children from accessing pornography on public computers. Sure, let your 7yo look at pornography, no problem, but if he says Merry Christmas to a classmate in school, woe to him!
Heaven forbid anyone should be offended! The US grants many and wide freedoms to us, but the right not to be offended isn't one of them. If a person is not Christian or doesn't celebrate Christmas for whatever reason, that's their right. But it's not their right to tell me I can't make reference to a holiday I celebrate. I don't have the right to tell them not to celebrate whatever holiday they choose just because it may offend me or I may disagree, and neither do they.
No one says Merry Christmas in an effort to convert someone. It's simply a friendly greeting meant in good will at a certain time of year, the same as hello or have a nice day and there's nothing wrong with it.
So say it loud and say it proud. Merry Christmas.
