Diversity that seems natural to the plot and diversity that seems to be the plot are treated very differently by different kinds of fans. The former seems to be well received even by people that aren’t huge fans of diversity. The latter seems to be grating on a large number of fans.
I actually really like social commentary, I don’t like tired, hamfisted, and insultingly performative puppet shows of social commentary. STD gave me vibes that a boardroom full of old white guys in expensive suits had a conference call with the writers that went something like “market research says progressive bullshit sells well to our target demographic, so I want 24 scripts about being ethnic or queer or something on my desk by morning. Make sure you really spell it out, too, the [slur]s are fucking stupid to get it otherwise.”
