A few years back, I was speaking to a roommate. I complained that the (then) new Star Trek had forced diversity. He immediately shut me down, “Star Trek has ALWAYS been like that”. He was a huge fan of Star Trek

Star Trek (TOS) never needed to BE about diversity, because it was set in a utopian future where racism, and sexism weren’t problems anymore. You had an entire multi-racial cast on the bridge of a starship so just from THAT you knew that racism wasn’t a problem in the future. There was no more war, poverty, disease or crime. Conflict only came from humanity’s meetings with alien races.

TOS Star Trek never needed to beat you over the head every 5 minutes with how gay someone was because that wasn’t a problem in the 23rd century. Nobody gave a shit.

Now don’t get me wrong, I think the best way for Trek to handle queer issues is to just put queer people on the bridge. A gay Riker equivalent or a trans woman who talks about her past with the same discomfort but honesty as how Picard talks about his is what I want. And in that vein I’m still on my first watch of TNG and it’ll be a while before I get to nutrek.

But I’m not going to pretend that to a certain portion of the population TOS wasn’t seen as being overly preachy on race. But seeing as I haven’t gotten to TOS yet either, I will say that in modern day I do think TNG was a bit preachy about disability and I’m glad they were.
