Well books can be a good way of going about it, lots of black oriented children's books. Plus my dad tended to be pretty blunt with me on certain things. If this was me, I'd explain how life in America is a competition or game and you have to be the best, then segway into the part where you have to go twice as hard if you black. If the kid ask why then you have a chance to explain. Always throw in the disclaimer that all yts aren't bad, and that they best bet is to just do good in school and stay outta trouble so they don't end up in a bad situation in like and by now I've brought it back to a neutral point and they ask about that and we can have a more general discussion. In other words, if its a young kid I'ma pepper the info in with a bigger overall point so they can recall it when that subject comes up later in life.
I can't stunt I've given a lot of thought on how I'd raise my kids if I were to have any. I can already tell I'ma be a cool ass parent.
