You should look into the history of how America has always done this. Perhaps start with how Birth of a Nation revived the KKK around killing Black men... or suffragetes saying lynch 1000 Black men a day if necessary. There's a rich history there that continues even now.

The great thing about the internet is there's countless pools to extract from. Academics, authors, statistics on incarceration, police murder, and school suspension, scholars, actual Black men discussing their experiences, youtubers. Even posters on here.W

We're conditioned as a society to downplay and rationalize the harm done to Black males, it's hard to received that information until you stop operating according to said contitioning and learn to see Black males as human beings.
