IOWs the only thing holding them back are their own choices.
The article keeps saying they are "stuck" in violent, crime ridden neighborhoods. You said it better.
“the only thing holding them back are their own choices.”
I think that’s true. They know if they speak and act correctly they’ll be criticized by their black neighbors and colleagues. So they “go ghetto” on purpose. And it seems to be pretty unique to American blacks.
I watch different house-hunting reality shows. The black couples in America speak jive or modified jive, and have amazing entitlement attitudes. The black couples in Canada are like all other couples and if your eyes were closed you’d never be able to identify the race. Of course, this is a generalization, but it’s true most of the time.
