Ah, 1969. America’s Gandhi was dead. Race riots had broken out in many American cities. The Cold War was at full tilt. But don’t worry! Here is “Let That Be Your Last Battlefield” to browbeat us with the message that “racism is bad”! Later, “The Mark of Gideon” tries to convince us that mass sterilization is the appropriate way to control population growth. Seriously, Star Trek? Go find an analyst. It’s socially acceptable to go to one. It’s 1969.
