That reason is called the First Amendment.
Specifically:
(Congress shall make no law respecting an establishment of religion,) or prohibiting the free exercise thereof
You two are the best FR has to offer.
Kudos and MERRY CHRISTmas to you!
Well if Christmas is to be celebrated in public school then I hope you won’t object to your child also celebrating a few major Hindu, Wiccan, Muslim, and Voodoo holy days as well.
Scenario. Kid comes home from school. Wow mom look at the picture I drew today. See, this is the Voodoo priestess praying to the goddess. Uh huh. We learned all about it cause today is a big holy day for the religion of Voodoo.
And we even had like pretend magic potions to drink and we danced all around too. It was fun mom!
Scenario two. Hi dad I had fun at school today. Today is an Islamic holiday. So instead of Arithmetic we saw cartoon of this kid who went on a pilgrimage to this place were thousands of Muslims pray to the Holy Rock. I prayed to the rock too but I was pretending.....kinda like.
Here’s how I see it. If a child wants to pray over her lunch at school during lunch hour, say a Catholic making the sign of the cross and quietly praying. That is a first amendment right. But that is entirely different from taking a whole class to a movie that has for it’s theme a Christian Holy Day. They need to be learning to read, write and spell, not having parties.
You take your kid to that movie! You teach your child about Christ and Christmas. That is Your job not a public school teachers job.
