"Race relations" is kinda wide topic, encompassing more or less the whole human history. It would be more useful if you point out which relevant aspects of this huge topic, in your opinion, the author got wrong and how, in your opinion, it influenced her discussion about education. I understand this could potentially also be huge, but at least 2-3 of major examples would be very helpful.
> I mean a school system that fails to take into account or fully address the same issues that I state above.
Yes, but address how? Any school system could fail to fully address one or the other aspects of the full history of race relations and social issues. It is impossible not to - it's the whole human history in all its vast diversity, and nobody would ever be able to account or fully address all aspects of it. Pointing out which aspects and how are not addressed would be much more interesting than just saying "oh, race relations, therefore whole article is invalid". I don't see how it adds anything, it just sounds dismissive of an experience of the real person and painstaking work she made of recording it and sharing it with us. What do you thing she have done wrong, specifically?
> It is hard to tackle these issues because it is still too hard to have a reasoned conversation on race
True, it is not easy. But I think that's not the reason to not try?
> The author of this article is part of the problem IMHO.
I do not see how. She honestly tried to help those students who want to learn and advance, despite harsh conditions that surround them, and she found her efforts consistently being contradicted and nullified by the system, which does not help people who want to learn, and allows people who behave destructively to continue their behavior not only to their own detriment, but to the detriment of others. She spent a lot of time and effort trying to teach people despite these circumstances and despite constant assault on her human dignity. If that counts as being part of the problem, what isn't?
