Interesting point. I do find it curious how Disco in particular caused such a massive brouhaha (even among existing fans) for being overtly sanctimonious when it was SO much quieter about it's politics compared to the other series. On TOS Kirk would essentially look directly into the camera and demand race-integrated schools. TNG's preachiness reached after school special levels of eye-rolling half the time. But Disco shows two gay men brushing their teeth and that's what upsets you?
Another example: I don't think it was possible for Adira's five-second coming out scene to be any more concise or unremarkable than it was and yet "shoved down our throats" was a common refrain. What exactly was shoved? I don't expect reactionary media to be logical, but I also don't know how anyone who actually watched the show could call it more performatively political than the previous series.
