Due to their current public schooling, both secondary and post, they are far too ignorant to learn from their mistakes. They have also been indoctrinated to believe they are owed everything without work. Their collective hubris is astounding.
I’ve noticed that most of the black students in NYC high schools that I’ve encountered have a hair-trigger mouth about their “rights”. You tell them, “Please remove your hat” or “You are not allowed to do ___”, immediately they spew, “It’s because I’m black!” out of their mouths. If you deny them anything at all or tell them about anything which restricts them from doing what they want, this is what you hear. They also believe that it is the teacher’s responsibility to supply them with paper and pens. They come to school without the basic tools with which to learn, they pay little to no attention to lessons, being too busy trying to sneak their cell phones out, they cut classes and wander the halls in herds, but they are the first to open their mouths about “their rights” when they predictably fail due to their own behaviors. I would say that their indoctrination comes from Al Sharpton and Jesse Jackson, et al.
