It should worry you. There are dreadful things happening in these spaces, and they are of such sophistication that children, and even many adults cannot fully ascertain.

The problem you describe is a cursed problem. You have so many malign influences being exposed that the only rational approach is to teach them as much as you can early to recognize and appropriately deal with these things.

That is easier said than done because at its core, you effectively have to teach your children how to lie, so they can recognize and discern the sophisticated lies.

There is also an element of biology, we call it the age of reason because there's a point where reason emerges, and prior to that point it isn't possible.

Prior to that age, they shouldn't be exposed. That will require a monumental amount of work because these influences are everywhere. Even in the Family movies (especially Pixar).

I would start following a classical education curricula (Trivium/Quadrivium) which includes philosophy, aristotle-in logic, Method, and reason.

Following that, there should also be education on perceptual blindspots, and its intrinsic link to communication, as well as how distorted reflected appraisal works (and its impacts). These are blindspot biases we all have as humans, and they will need to know and recognize the limits to defend themselves.

Robert Cialdini wrote a book on the levers of Influence. Communications should roughly follow an Intro course that you see in college with particular emphasis on perception, uniquely shared meaning, deceitful or manipulative structures, with guided exposure towards the end, relating to deceitful, misleading, and false narratives.

The basis requirements for torture should also be taught, so they can recognize it when it happens to them. Coercion should be fully understood so they are not helpless when its eventually applied to them. This should also include how you handle people who lie and how to case-build, and employ countermeasures in such areas.

Being capable of retaining rational thought under applied stress at higher amounts than others, will offer them the best chance at survival.
