What don't you like about Christmas?
The legions of morons ranting about some imagined "War on Christmas". They usually begin their rant with some variant of "They won't let me say 'Merry Christmas'" and ends with a "defiant" "Merry Christmas". Whoever "they" are that prohibit the phrase apparently don't do much to enforce their edict.
I'd hesitate to call it a war, but there have long been some people who have something against Christmas and how its celebrated. And it isn't enough for some to merely not observe it themselves, but to try belittling or minimizing it in some way. And, yes, there are some who do try to enforce others from saying "Merry Christmas," for example employers who berate or criticize staff for not using the politically correct phrase of "Happy Holidays." I've actually seen this done. The whole "not wanting to offend" is also a bogus argument since the only ones offended are the ones who dislike the holiday in the first place.
I don't care and can even respect if someone doesn't want to observe Christmas, but why do they have to go out of their way to piss on it for others? A rhetorical question since I don't really expect an answer and this isn't the subject of this thread.
