No, it's separating empirical studies from personal beliefs. It is up to one's family to teach them their family's cultural traditions...and up to those same parents AND the school to teach them Math, Science..Reading..writing.
Same reason Walt Disney and Dr Seuss are not regular public school classes, n'or should particular religions be.
Ah, but Dr. Seuss is often read to children in school, and schools often show Disney movies. Do you know how many schools teach math today (thanks to No Child Left Behind and Common Core? Parents have no say as to in which classes their student is placed. They have no say as to the math, history, and science curriculum is being presented. Many parents who would love to help their children with math often give up at the middle school level--not because they do not understand math--but because they do not understand how math is being presented. Make the parents feel uneducated themselves, and they certainly are not going to show up at school board meetings to protest. Same with religion. If parents feel all they have are "personal beliefs" and all the teacher has is another set of "personal beliefs" the populace can be kept quiet and in their place by their "betters". Religion is much more than "personal beliefs."
It is a no-brainer that had you been taught religion and the philosophy of the human spirit properly, you would not now be discussing these topics referencing a "sky daddy."
Ignorance should never be the preferred antidote or answer to anything.
