When is the holocaust and other info about historic anti-semitism introduced?
I would be surprised to hear that they delay this, I believe some of these historical stories/events are part of their religious studies as children.
Giving the oppressive system a pass for X number of years and letting children walk through society ignorant of the threats they face is an even bigger disservice that any demoralization that may or may not occur in my opinion.
Black children literally get murdered by the state for benign activity, I think by 13 (the age Tamir Rice was murdered) they are old enough to start learning why.
