KKK members showed their faces publicly at a children’s soccer field in the 1970s

Evidence

But there were clear episodic reminders that while my fellow black students attended the same schools and had the same teachers, we still lived in strikingly segregated social worlds, and that when those worlds overlapped, my black classmates and friends were tenuous guests in a world of white dominance. … On at least one occasion, I recall seeing Ku Klux Klan members in full white regalia, handing out white supremacist pamphlets and collecting donations at the red light while we were waiting to turn into the park for a game. From my perch in the back seat of our gold Chevy Impala, I remember being struck by the fact that their hoods were pushed back to reveal their faces openly and that one of the men was holding his son, also robed, who was a few years younger than me. — Robert P.
