Several centuries worth of deeply ingrained racism?

Maybe, but I think there is more to that.

As a personal example, I have immigrated into US from the country with almost no black population, so I'd say that "several centuries of deeply ingrained racism" do not apply to me.

Within the first year of arriving into US, I've had been verbally attacked while I was riding the bus and reading the book. A bunch of teenagers started to say things like "he looks too smart" and "let's take his book away". For a high-schooler who had no exposure to violence before this was pretty scary. Since then, I tried hard to avoid riding the busses through that area. Can you guess which race were those teenagers?

(Note that I have arrived with some pretty weird believes, like the one that everyone with shaved head is a gang member and had to be avoided. That one did not last very long, because there was one person with shaved head in my math class and he was pretty great. Unfortunately, there were no similar experience to persuade me that I should not avoid groups of black people.)

Do you come on Hackernews every 2 years to write racist things? Your last comment is from 2018 and has the same white supremacist talking point.

OK but why is it perpetuated today? My contention would be that it is mostly popular entertainment, movies, music, and media that perpetuates this view of the aggressive black male.

I have had little exposure to black people in my life. The few that I have encountered in school or professionally have not demonstrated any aggressive nature. I have no first-hand experience of aggression by any black man. My parents did not teach me that black men are aggressive. I did not learn this in school or from my friends. The only way I can think of that I might have gotten this impression is from movies, television, music, and media. These are the same people who are now professing and demonstrating how woke and concerned they are, rather than apologizing for their roles as the primary perpetuators of a stereotype.

Therefore when I see media or entertainment figures (I include politicians here) on the anti-racist soapbox, it all falls rather flat for me. They are the ones fanning the flames on one side, and demanding attonement from everybody else on the other side.

You are making my point so well that I'm worried people are going to think you're a sockpuppet.

Obviously, my neighbor should not be called on to answer whatever sins you think the culture has incurred.
