You think there's a problem reminding readers that venerated people aren't good role models? Why? Why not strive to be better than them, intentionally moving past their flaws?
I think that attitude would be great, but that isn't what I see happening. There is a widespread movement to cancel basically all famous historical figures, and dismiss the value of their work along with discrediting their personalities. It's frustrating to see, since many of these people were really inspiring to me as a kid, making me want to be a scientist/engineer myself.
