Gene's vision!
Code of Honor
At the time back in 1987, watching the episode, as Chris stated above, was an improvement having a plot where the crew beam down and every single person does not look like the meeting of a wanna be WASP convention. It was worse when they came across a human populated planet, I think it was only
The Masterpiece society that had a 'diverse descendants from Earth' population.
When VOY came along, some fans could not handle a brown skinned Vulcan, after all beings from a predominately, very hot,
desert planet can never have brown skin right?

I did not consider
Code of Honor racist at the time, I did not know the racial attitudes of the director but he did not write the script. As a brown skinned human I am not entirely convinced of the '
Code of Honor is racist' argument, since as far as I know there are no brown skinned people on a real life Earth that fit the portrayal on the show.
I think the love interests of the crew were more racially close minded, its the 24th century and every time Picard, Riker, La Forge, Crusher have a romance the love interest has the same melanin content that they do? The only exception were Worf and O'Brien.
At least DISC broke the mode in that department!
