That said, the parent poster said that many leadership positions, plural, were filled by people of color. I think it's probably reasonable to say that a community of many political leaders of color are more familiar with systemic racism. These are folks who specifically choose to get involved in politics and leadership, and likely represent fairly large constituencies. It's not unreasonable to assume that they broadly have experience or are able to communicate with their communities that have experience with systems that negatively impact people of color.
