I get that you're of the opinion that telling people about racial inequality can demotivate them and make them feel fatalistic about their futures, but I don't necessarily agree with your assessment to the degree this is the case and you seem to think there is no room for nuance here. We must stop talking about this immediately. People are too simple to understand that there is still some unfairness that needs to be resolved, but that they should do their best regardless. No we must lie to them and tell them the system is fair and through their ignorance they will magically overcome the disadvantages they face.
You seem to think fear of systemic racism is a bigger obstacle to the success of black people than actual systemic racism and I just think that's absurd. Your basic premise that fear of institutional racism can be demotivating is valid and worth consideration. You're elevating it to the root cause of all problems is absurd. A black job applicant will receive half as many callbacks for job interviews compared to an identically qualified white applicant. There are little obstacles like that all over our society. Can they be overcome through tenacity and perseverance? Yes. Does that mean we shouldn't work to fix that %#@#? Hell No!
