The so called “war on christmas” is something atheists like to make fun of because there really isn’t any war on christmas – it’s all about being more inclusive like this meme says:
They might have a point if any of these “december celebrations” besides Christmas and Hanakkah were big holidays, but they aren’t. They’re not even little holidays. Most of them are fringe bullcrap only celebrated by antisocial weirdos.
Funny enough, I live in a liberal, diverse area – with many jews – and nobody ever gets angry if you say “merry christmas”. Nobody has any problem saying merry christmas back unless they can’t speak english.
It really seems to be an atheist thing. Most Atheists are antisocial weirdos like the people who celebrate Kwanzaa and they are in fact trying to sabotage the holiday.
Bottom line is you don’t have to make room for cultural practices that don’t exist where you live, but if you don’t want to acknowledge the practices that are common then shut your mouth.
