The real problem with wishing liberals a merry (or happy) anything is not that it may offend them, but that it seems like an exercise in futility. Wouldn't the wish "Tearless Tolerance" be more appropriate?
Conservatives Like "Merry Christmas"; Liberals Like "Happy Holidays"
Ah, liberals. They really are a breed apart (mostly from sanity). And a timely example of how we're a divided nation concerns the conservative/liberal dispute over how to greet people at Christmastime. As the Star-Telegramreports in a piece titled "'Merry Christmas' or‚ 'Happy Holidays'? Your response says a lot about your politics":
Two-thirds of Democrats (66 percent) said stores or business should greet customers with "Happy Holidays" or "Seasons Greetings" instead of "Merry Christmas" out of respect for people of different faiths. Two-thirds of Republicans (67 percent) said stores and business should not go with the religion-neutral sayings.
