That has been the case for a long time, and I guess something about the current generation of parents has gotten them to act more on it. My dad came from a very religious family and they all did private religious schools for their early grade school years. Then they went to public for high school years.

If I had to guess, its maybe something about the demise of church life that has gotten religious parents to just pull back entirely. It wasn't that uncommon for public schools to make nods toward Christian ideals/lifestyles before like the 90s, but now that stuff just doesn't happen anymore.

States are saying that schools have to post the 10 commandments and when teachers put up a poster about “everyone is welcomed here” showing kids of different colors it’s “too woke”.

Which is funny since I (a Black guy) went to a mostly White Christian school in the 80s where they sung “Jesus loves the little children - red and yellow black and white they are all precious in his site”.

Schools should absolutely teach Christian mythology and history, and Greek mythology and history, and Egyptian mythology and history, alongside many other subjects. But to the extent that they used to make "nods" towards "this is the cultural default we defer to", nope.
