I don't exactly agree here with either of your statements.
With the morgan freeman one, racism isn't caused by people talking about racism, it going to exist whether we discuss it or not. Since its going to exist either way, its important that people talk about it enough that we stay educated and know everyone knows what it looks like and why its wrong. I think thats extremely important even if it ends up with the big fusses you mentioned, after all I'd rather live in an age where people argue on twitter about minor problems than an age where big problems go unchallenged.
For the Yuka's presentation thing, i think its more complicated than how you presented it. Yuka does feel like they* have to fit a mold but its not that their friends are doing that to yuka, more like a self identity problem that yuka has been dealing with internally. In my opinion they could be trans or a crossdresser and there's more than enough evidence to support either side. I don't think its about bigots trying to force yuka into a "wacky category", but people noticing that yuka does a lot of stuff that fits trans people better than crossdressers and interpreting yuka as trans because of that. There are a lot of legitimately trans characters that the authors dont call trans, so those people might just be getting defensive about a character they relate to being smudged into a perspective that doesn't consider them.
If you want I can outline the reasons why I, as a trans person who knows other trans people and crossdressers, consider Yuka to more closely resemble a trans person than a crossdresser. I don't think that's currently relevant though, because I don't have a definitive view of Yuka's identity anyways and im not asking you to see yuka as trans
*im using they because this character has gone from using masculine pronouns to feminine pronouns and i can't tell when they are using which because of the translation so i cant make an accurate opinion on how the character uses pronouns. Especially since this chapter brings into question whether Yuka actually prefers feminine pronouns or they feel like they're supposed to use them, which is a huge can of worms for a lot of reasons
