Excellent point to make. I'm glad Oklahoma is now integrating The Ten Commandments into public school curriculums. If I was to write a textbook for that, I would spend most of the book focused on the Fifth Commandment. "Honor thy father and thy mother".
If I was teaching such a class in K-12 public school, I would tell my students this: "If yout parents are crazy, it's because you made them that way."
