For example, Zoey's Extraordinary Playlist gives the impression of high representation of minorities in tech (Sprqpoint is extremely DEI friendly being a woke silicon valley tech company, but even the main character's non-techy neighbor is a black genderfluid woman dating a gay black man).
The Dragon Prince gives the impression of high representation of minorities as well (with 1 main character and his kingly father black, 1 main character having gay parents, the rulers of the neighboring country being lesbian, etc).
I'm not saying that's wrong, just that minority groups don't need to make up 126% of TV actors in order to be overrepresented in main cast.
Heck, even outside of media, look at the Supreme Court. Soon 2/9 justices will be black, which is 22% of the court - an over representation of the black population. Again, not that I have a problem with that, just that DEI efforts can cause high visibility groups (such as a TV show's main cast) to be overrepressented by minorities.
