I wrote a blog post similar to this about letting Black children be Black children. I found it extremely disgusting that Black children as young as 9 years old are treated like adults. It all stems from dehumanization. The want to dehumanize every person of color even if they are innocent and small children. I think one thing I would add to your question is to make it specific to Black children. How can we get White adults, White people in general, to learn about the dangers of prejudice and dehumanization toward Black children? I think that this is something that is taught through environment and social networks. Are you surrounding yourself with people different from you? Are you trying to learn about different cultures? There are so many things that the White adults should and need to partake in.
