gonna play "devil's advocate" by giving my thoughts on what I think people are after.
they need characters to actively get dirty looks and be treated differently by those who normally are nice.
like if someone is talking nice and normal to say Coco, and then Velvet comes up and the other person just looks at the ears before giving Velvet a dirty look and then gives a remark before leaving. that is at least the bare minimum of the type I see some "people" wanting. they want it more actively present and from more then just those we already know are dicks (Cardin and Roman).
they want more dirty looks, more harsh comments, and maybe some stuff occasionally thrown, because to them when you put such a big topic like "race" in the narrative they expect it to be a bit bigger and a touch more noticeable.
and all this is on top of an audience that already has trouble seeing the subtext, reading between lines, and just general understanding of these things and the mindset of the show creators.
both "show, don't tell" and "death of the author" can go suck it.
EDIT:
for another topic here is my two cents on RWBY VS ACEOPS;
So many haters think that RWBY only because of "Power of Friendship BS" and thus mark it as "Bar writing, but it was not the "power of friendship" alone.
Yes it was set up that the aces are awesome and skilled, but what did we also see at the close of their debut fight? Ruby making the save in time by grabbing that dust crystal. After that mission Harriet brought up how they aren't friends but "trust" that they have each other's back. Then we eventually get a montage of how Ruby and friends end up spending a few weeks in Atlas. They are doing missions and training under the guidance of the aces. During the invasion we see Ruby and friends working right alongside the aces as equals, and again we see Ruby's quick thinking save Harriet's ass. And finally in Ironwood's office and then into the fight itself we see Team RWBY united. They are on the same page. Meanwhile the aces' minds are rattled and their unity is put off their game. Marrow clearly is uncertain about things, Harriet has tunnel vision on Ruby, and Vine and Elm (the only members who managed to stick together) are clearly not on the same page.
We got set up (the entire mine mission), the build up (the training montage and the invasion), and the pay off (war in the academy).
other arguments are "Ace-ops don't act like real special forces" "real special forces don't underestimate their opponents" "they forced the fables"
