I don't know your parents or their situation, but I can speak **generally** about godless government education.
In my homeschool, when we read literature, I would point out to the children which of the Ten Commandments had been broken that caused the fictional conflict upon which the story was built. In fact, except for the genre of “Man Against Nature” it's darn hard to write fiction that does not include the breaking of a Commandment!
Imagine that being taught in government school! Fat Chance!
Yet, to ignore even this **one** tiny aspect of including the Commandments in classroom lectures leaves the child woefully poorly educated! Teaching the child to evaluate literature in a Ten Commandments-free vacuum weakens a child's faith!
This is merely one example among possibly thousands in which learning how to think godlessly weakens faith.
The above is a **general** statement about education. I don't know your parents or their situation and have no comment about them.
