Star Trek, sexism, racism
Yes. In defense of Star Trek, they often pushed against conservative ideology, but had to keep reasonably under the radar or circumvent it.
For example, the Uhura--Kirk kiss had to be done when the morality chaperone wasn't present.
Also the more revealing female mirror uniforms had also to be hidden from the chaperones.
The female uniforms are an interesting story in themselves. I used to think they are terribly sexist until I found out about its story and how it falls within 1960's fashion and the discourse of women's liberation at the time.
Star Trek has a lot of problems (eg. Ferengis) but it also did a lot of good things.
