TOS put a diverse cast front and center on the screen, including folks hailing from nations that were currently/recently enemies of the USA at the time
Yes and they had that diverse crew naturally work together as a team of professionals without loosing a word about it, instead of constantly reassuring each other and the viewer in dramatic pep talks with a lot of crying that it´s ok. That is exactly the understated wokeness I miss in NuTrek and appreciate in classic Trek.
Geordi turned the concept of what it meant to be ‘disabled’ on its head felt really pointed.
Agreed but that worked so well because Geordi being a full member of the crew was presented as something completely normal. There are no tearful pep talks to reassure Geordi that he’s a full fledged member of the crew. That would have been unnecessary, because it’s shown as just natural that he was. Another example of the understated, smart wokeness in classic Trek. This is the opposite of NuTrek wokeness, which constantly gets overstated and rubbed in the viewers face, like the viewer would be a mentally challenged bigot, who could not grasp the concepts of tolerance an humanism on their own.
