An interview with Star Trek creator Gene Roddenberry on Good Morning America from 1986 shows how many serious issues Trek actually tackled, including the Vietnam War. Roddenberry talks about dealing with push-back from the network, Desilu studios and his advertisers on issues like the inclusion of Lt. Uhura as a bridge officer. And he says the idea that we shouldn't discuss anything serious on television is "a criminal statement." [From A Sci Fi Stand Point]
