But it did, in many ways. His choice to have the cast be multiracial and harmonious was a direct comment on the times. And there are plenty of episodes where racial intolerance was explored via the aliens the Enterprise encountered. Star Trek is great specifically because it engages direct with the times in which it was/is made.
Yes, but Roddenberry was specific about what aspects of humanity he believed we need to improve (racism and ethnic divisions). Given the proximity of ST to the major events of the Civil Rights, this would have been at the forefront of people’s minds when watching it. Later Trek shows went on to explore that in more depth, most notably DS9, which engaged most directly with American racism, and dealt with issues of colonialism/colonial violence, war, and the impact of those on people’s lives.
There’s stuff like this, too.
