I get that "white people solve racism" is an annoying thing in Hollywood movies, I really do. But sometimes it really was the case that white people of character actually intentionally chose to make a difference in the field they controlled, and Branch Rickey was one of those people: he signed Jackie Robinson out of business sense and idealism. The business sense doesn't cancel out the idealism, which was significant and showed up in other areas of his life, too. Which you would know if you bothered to learn any of the story, as the author of the above-linked post obviously did not.
Excuse me: University of Michigan alumnus Branch Rickey.
