I track with this big time. Another part of the fallout from that lack of nuance is the suppression of celebrating people who come from privilege that then decide to sacrifice (sometimes suffering way more than the folks they're helping) to fight for the disenfranchised. The problem is not that William Wilberforce or Levi Coffin somehow need veneration. They're dead and they either have their contentment in heaven or none at all depending on your worldview. It makes no difference to Harriet Tubman or Levi Coffin which one you celebrate more.

Who it does make a massive difference to are the disenfranchised people today. If the next potential Coffin isn't inspired (not for glory, just for lack of awareness of what they could be), the only people left to do the work are the bootstrapers. By definition, they have less resources to contribute! It totally betrays a lack of concern for the disenfranchised when professors, museum curators, influencers, or other various blowhards downplay the sacrifice of people that chose to be a part of the solution in their generation.

Do you read Siddharth Kara's books? I'm currently almost done with The Zorg. It's more than a little depressing, but I bet you would find it insightful as well. He does a good job of critiquing the British without letting the Asante or others off the hook, and celebrating the heroes without respect to their background.
