Either these people are trained to speak prescriptive English or they are barred from academic success. The argument of the article is that the treatment of the language causes this ongoing social issue, not that the social issue is preventing people from speaking American English.
Any honest person can see that those of us with more "respectable" US accents form the real criminal culture. We took the land from people we exterminated, took slaves of people whose dialects we still ridicule, and to this day imprison and war like no other humans in the universe.
That decisionmaking power is less than in a real democracy (a top-down republic with some democratic forms), but more than a dictatorship. So there's some shared responsibility which does not exist in your examples of other groups.
I speak standard english, but am part of a minority group that has been tortured and killed for thousands of years. You don't speak for me. Or for my friends, who aren't all part of my minority group, but some of whom also speak standard english (and sometimes are or are not part of their own minority groups, while also some majority ones). I'd say you don't get to speak for them, either.
I have not taken any land nor exterminated or enslaved any persons. Stop stereotyping based on skin color. It's really racist. Racism against any person is not ok. I don't care who you think it will make you a better person if you hate.
"to this day imprison and war like no other humans in the universe."
All humans imprison and war, not just white people.
Africans and Asians can be just as cutthroat, if you have any knowledge of history whatsoever. Cruelty is not copyright Caucasian, as has become the political correct fad of the last few years. It's disgusting.
It's like, I personally don't like rap, but I wouldn't begrudge others who do because they see something special in it that I simply don't see. I used to, until I realized it wasn't simply that people were being "stupid" by listening to rap, but instead that I was missing what they were seeing.
(Sorry to be a prat, but it was so deliciously topical.)

So I disagree it wasn't "all me" and it wasn't bigoted.
