This.
What he is saying is 100% right. The perpetuation of ignorance within Black culture is dumbing down our successive generations. Little kids have no business singing the lyrics to songs like "Birthday Cake", I cannot possibly fathom how anyone could disagree with that.
And the whole "parents should monitor..."....that's an EASY answer. Of course some parents monitor what their kids see/hear, but only WHEN that parent is around. They're not with their kid 24/7 - at school, at sports practice, at any other place where parents NEED to send their kids in order to promote healthy social skills - so it's impossible to filter out all things deemed negative. Further, throwing it ALL on the parents shirks the culpability of the artist. And I'm not of the belief that artists don't have a responsibility with their craft.
But that's just me.
