We have concluded that snark must be nature’s way of forcing the child away from the parents in order to venture away from the nest. We are officially un-cool in his eyes.

Could be the influence of snarky brothers and sisters, although there is probably some truth to what you're saying. My homeschooled daughters are 15 & 17, and we've yet to experience teenage snark mode, although they are capable of speaking for themselves.

There is no historic or biblical basis for accepting “snark” from children at all. This is a fairly historically recent development, and it all comes from the rejection of traditional (biblical) values.

Children obey your parents, honor your father and mother,

neither have a “unless you’re a teenager that knows better than your parents” caveate.

Same here. There was no "teenage rebellion."

Maybe it's a government school indoctrination thing. Kids are taught their parents, their traditions, their beliefs are all wrong. Only socialism/communism are politically correct. The kids get confused, because parents do what they do because they love their children. Schools do what they do because they love the power and money. The kids get hurt by this in the end.
