what those posters are teaching kids is that a racial hierarchy exists, and that they will need to adapt to their correct place within it.

the people that did the actual postering are no doubt completely brainwashed, and at little fault. and, you can't argue with people that are under the control of these methods, either.

what this is is a psy-op. it's an evolution of the tools that people like edward bernays invented a hundred years ago. and, if they have their way, we will all be placed in our right places, in this neo-burkean structure - with white people as rulers, and everybody else as slaves.
