The best parents are the ones without kids - not true, but those on the outside can only observe and make judgement because they don't benefit from the relationship.I agree to a point, because I'm not a fan of religion. It's too boxy and limited. A relationship with God - that's something different entirely.
I wouldn't really classify your comment as a rule, it's more of a snippet or discussion starter.
Sometimes it's a rule like, "You should do this..." but this is more of a rule as in "As a general rule... if X then Y."
If your comment is too long, break it into multiple comments and post them all.
