Except those weren't the entirety of the complaints with many of them elaborating to point out why it's a problem / doesn't make sense / makes the character awful and seems like poorly done writing because.
General refuses to trust her best troops to know a plan that seems initially suicidal leading to them taking it upon themselves to try and save the day fearing defeat due to the plan they got told not being the true plan.
Also Barely characterised Asian character saves hero with one that she's apparently been madly in love with but we've not really had much development of that or her as a character before that point.
Okay, in isolation, those are reasonable criticisms. However, the thing is, a lot of the time, those criticisms weren't made in isolation.
Holdo wasn't criticized just for poor command decisions, she was called "Admiral Gender Studies," and it was seen as an attack on men because she lectured Poe.
Rose wasn't criticized for being a lacklustre character, she was criticized for being an example of "forced diversity" and "pandering to the Chinese audience" (the fact that Tran is Vietnamese notwithstanding). Even your own analogy conveys this bias when you call her "Asian character."
It's easy to dismiss critics by framing things certain ways and being less than honest and using weighted words reliant on people not looking into actual complaints just going for soundbite moments on social media.
Bigots just hated the Diverse cast - Suicide Squad.
Sexists intimidated by good looking female lead - Alita Battle Angel
Homophobes slam movie due to black lesbian - Ready Player One
You're right, it easy to frame those things, but for the Last Jedi, those framings weren't required, they were verifiable. I had the misfortune of seeing it with my own eyes on Wookiepedia, as I reverted people's edits to Rose and/or Tran's pages, calling the character/actress a "*****." If people are acting like assholes, and are displaying their assholery, it isn't some media conspiracy to treat assholes like assholes.
Also, your hypothetical equivalents don't work as:
-Suicide Squad: The film wasn't even diverse in any meaningful manner, and none of the criticism levied against it really touched on the issue. People generally agree that Katana was terrible, but also generally agree that Will Smith and Margot Robbie did as good a job as the material allowed.
-Alita: You mean the film that got drawn into a culture war as some kind of stupid rivalry between it and Captain Marvel, because Brie Larson said some mean things?
-Ready Player One: The film wasn't slammed (it was generally well received), and I've never seen anyone focus on film!Ache (I will say Ache is handled better in the film than in the book, but that's another matter).
You're comparing hypothetical criticism and hypothetical reactions against verified criticism.
And yes, I can fully admit that what you described can happen - see the excuse for the Charlie's Angels reboot, where the director blamed males/boys for see Marvel movies instead of her movie or something. But I don't recall Disney/Johnson doing that, and even if they did, it doesn't change the fact that a lot of criticism WAS sexist/racist.
Oh, and are we forgotting how Disney reacted to it? You know, a piece of drek called Rise of Skywalker, that no-one seems to like in any part of the fandom? Where Rose is effectively written out of the film, among other things? Remember that?!
Except now they've kept that level of writing but the male character never gets a moment. The female character just saves the day while the male character I dunno falls over his shoelaces and faceplants the floor or something.
Often with added film dialogue about how men are bad or how the future is female or something like that.
What the hell are you talking about?
Okay, maybe there's some film that does that somewhere, but this is hardly some kind of trend. Look at any major film franchise, and male characters are still dominant. DCEU, MCU, Wizarding World, Star Wars, James Bond, etc. Look at the highest grossing film franchises, and you'll find that there's far more male roles than female ones.
In fact, I challenge you to name a film that waxes lyrical on how men are evil. Because while those sentiments do exist in the depths of the Internet, and even on published sites such as Medium (which is filled with that kind of stuff), the idea that films are these bastions of wokeness? Not really. Crazy as some feminists are, I disagree with the notion that they've got this supposed mega level of control over the arts.
