You're completely
mischaracterizing the criticism. No one here is complaining about race or gender etc. Star Trek and most other sci-fi has always been diverse, it was the core component of Star Trek and is one of the reasons so many love it.
As was mentioned above DS9 did it right, leveled up diversity. Sisco was not white but no one cared, I've heard many name him as their favorite captain. DS9 is my favorite ST spin off, and Janeway was also a well written and well played captain.
Folks are calling Duhscovery out for "forced diversity" because it's not "leveled up" anymore. The women are not only the leads (which bothers no one) but they are the only strong competent members of the crew. The men are either incompetent, villains or both. They are always failing and needing the women to do their jobs for them.
Spock was established in this show as awkward with a mental disability who needed Burnham to teach him how to be a good Vulcan. The implication here is that all of Spock's great accomplishments were only possible because of Burnham. Same thing with Star Wars, the original heroes were failures and the amazing and all powerful Rey had to finish their job.
Inclusion is great, I've always been for it and have enjoyed it in the many franchises I've watched all my life. But the current trend is to elevate one group by lowering another, this is not inclusive or equal.
