Regardless of your religious affiliation or lack thereof, you have more than likely heard the "Happy Holidays" vs. "Merry Christmas" debate. The political correctness police will chastise you for wishing someone "Merry Christmas," and it's time we break down the ridiculous nature of this argument.
"Not everyone is Christian. You can't push your religion on them by wishing them a 'Merry Christmas.' It could OFFEND them," they say. Let's take a moment to analyze this. If you are wishing someone a "Merry Christmas," you are wishing them joy, love, peace and good times with their loved ones. Clearly, these are not abrasive things to wish on someone. The reality is that it does not matter at all what religion the other person does or does not practice. What matters is that you are wishing positive experiences on someone as a kindhearted stranger. If you are Jewish, wish someone a "Happy Hanukkah" or if you're into celebrating Kwanzaa, say that. Christian? Then say "Merry Christmas." Or don't say anything at all. That's your choice. All of the holidays around this time of year are meant be positive and joyful times.
The First Amendment gives us freedom of religion and freedom of speech (and freedom of the press). The Establishment Clause of the U.S. Constitution states that no single religion can be established, essentially as a "national religion." It is your right to say "Merry Christmas," "Happy Holidays," or whatever holiday you celebrate. The point is that it doesn't matter what the recipient of your good wishes practices. It is not offensive, and you are free to practice whatever religion you want as long as it doesn't include illegal acts, and you are free to say whatever you want within reason (see the falsely shouting "fire" in a crowded theatre example for more clarification). There has been a misinterpretation of the First Amendment's freedom of speech and freedom of religion rights for quite some time. You can say whatever you want to whomever you want, even if what you're saying is offensive. As long as your speech isn't 1) obscene [click here to see how the Supreme Court's definition] 2) defamation of character [libel and slander] or 3) "fighting words," you are exercising your right to free speech as it was originally intended.
All arguments aside, please do not be concerned with offending someone by wishing them good things this December. Love people, spread joy, relax and spend time with your loved ones. This time of year is meant for you to reminisce with loved ones about the shenanigans of the last year, to create new memories with those you care about and to send good wishes others' way.
