A propos, in an editorial, Michael Granger at You Don’t Read Comics shares his personal experience regarding Blue Marvel as #BlackSuperman and racism:

Some people love street-level heroes, Batman, Black Panther, Daredevil, and Spiderman, and so on. But my heart always had a place for the big heavy hitters, and finally, here was one that looked like me, who experienced racism, and whom I related to directly. As someone whose parents and uncles were raised in the Jim Crow south, who attended a predominantly white high school, and as a soldier, I couldn’t help but relate to the character.
