No, its not. (Isn't this fun?)

Having spent much of my childhood being called a "nigger" by White Americans (and some, though less, being called a "zebra" or "oreo" by Black Americans), I really don't need any lectures from anyone about what "most White Americans" don't get about race in America.
And while there are certainly many things that many (or even most) White Americans don't get about race in America, what some (but, IME and AFAICT more generally, not most) Black Americans (and, even more paternalistic white-knighting White Americans) don't get is that negative racial stereotyping both is and promotes racism no matter the race of the proponent of the stereotype or the race targeted by the stereotype.
EDIT: I wanted to add a comment on this:
> Certainly, I don't think pithy tweets are the best way to advance these critiques, but they're not being written for the benefit of cerebral tech bros like us, they're being written to offer some relief and solidarity for others whose lives are materially affected by white bullshit.
The fact that a racist utterance provides some relief to an audience that has had negative experiences doesn't make it any less racist. Heck, one of the main uses of anti-black racism by white economic and political elites in the US has been to offer some relief and (illusion of) solidarity to poorer white Americans suffering from adverse conditions by directing the blame at blacks in general.
