I would never go to any worship service as a tourist.
And you should never teach your children that Christmas is a secular holiday, because you would be lying to them. Of course, as an atheist, I guess that's not a problem.
Anyway, have fun on Santy Claus day, and remember, if you try to secularize Christmas and pretend it's something it is not, you are a hypocrite.
I don't have a problem with atheists, it's not their fault, but don't try to horn in on someone else's holiday because you think it's fun. You can have it both ways only if you are a hypocrite.
Christmas is not a secular holiday.
Oh, c'mon now, you DO have a problem with people who don't share your beliefs. I think that's pretty apparent. But, imho, it's a free country, or at least it should be, and you're entitled to the right of disliking people.
But if you think that Christmas should be observed as a federal holiday, that Christmas traditions should be celebrated in public schools and in taxpayer-funded displays, how can you turn around and say that the same people being forced to observe/celebrate it should not participate? Now THAT'S hypocritical.
Btw, if you don't want other people "horning in on" your holiday, then maybe you can start a movement to take Christmas off the federal holiday calendar. While it's there, it IS a holiday for all of us, Christians, Jews, and even atheists.
If it hadn't been named as a federal holiday, you might've kept it as sacred as you'd have liked, only celebrated by "true Christians." By making it a federal holiday, observed by all Americans, all the secularism was invited into it.
