civil rights/racism/history stuff
Subtweetish but I wanted to call people's attention to the Port Chicago Disaster and subsequent "Port Chicago Mutiny." I think it's an amazing civil rights story you never hear about as part of some fairly early pushback against segregation (not just because of American racism, but also because it hurts our image as the good guys only in WWII) and one of the most prominent people involved in getting support for the "mutineers" was a fairly young Thurgood Marshall, long before he became a Supreme Court justice.
