Crunchyroll and Netflix are sitting on production comitties, directly influencing the anime that gets made. The creator of one of the most popular isekai series SAO recently stated that it was western criticism that made him rethink the way he writes female characters and will make an active change to improve them.
My own take is that many viewers are unaware of the underlying messages and themes of the works they are consumimg and then over react to the critical analysis of the issues people have with those themes. When you watch a show where slavery gives the slaves benefits and people want to be the MC's slave, where women you are sexually attracted to actually are "sluts" and they live in a "matriarchy" and that means a false rape accusation will ruin your life and no-one will ever want to be with you, and instead you should get a 10 year old child slave who's interactions with you will cause her to "level up" into an adult body whilst keeping the mind of a child - you have to ask yourself what exactly the author is trying to tell you.
Storytelling is not magic, pulling plot lines from the aether; the author made a clear decision to use these themes and these plotlines in his story. The fact that people can't see what the issue is more troubling than anything else because it is this that allows them to be co-opted by the alt-right. When you have no eye for literary criticism then if you tie your self worth to your enjoyment of flawed media any criticism of that media feels like an attack on you personally. It's hard for someone to say "I accept this show has themes I find abhorrent but I still like it because ..." But it's important that we ALL learn how to do that. I listen to rap music which glorifies some terrible moral standards that I would never live or defend in reality, because I know it is not reality! I can clearly make a distance between my own standards without making an excuse for those in entertainment. I don't think people are bad for liking flawed things, I think people are bad for not accepting the things they like can be flawed because to me if you can't see the clear themes in the media you are consuming - how can you then claim to see it when those same nuances appear in real life?
I hate the fact that so many people associate anime avatars with alt-right nonsense these days, considering that it was precisely because of my exposure to anime and anime-esque games that I moved from being a center/right Catholic to a super left Agnostic.
OG Sega CD Lunar: Eternal Blue taught me the dangers of blind faith in a so-called deity and it's supposed followers.
Evangelion taught me that self-loathing accomplishes nothing, while the opposite problem of an over-inflated ego is just as destructive.
Metal Gear Solid (yeah I considering it anime-esque) taught me more about the dangers of nuclear weapons than school ever did.
Revolutionary Girl Utena completely changed my perspective on the idea of societal gender roles and sexuality.
A particular episode of Cowboy Bebop (the episode where Jet runs into his ex) clued me in to just how toxic the male idea of "taking care of your woman" can really be.
Additionally Cowboy Bebop also taught me how holding onto the past can prevent you from looking forward.
While I don't have a specific example on-hand, countless anime have stressed how even if a person/society presents you with just limited options, you don't have to listen to that nonsense and can find your own solution that doesn't conform to what they demand be the only ways forward.
Loathe as I am to mention this one considering what we now know about it's creator, Rurouni Kenshin taught me that it's never too late to try and change for the better, to redeem oneself. Just because one was "bad" before doesn't mean they're thereby locked into being "bad" forever, so long as one genuinely work hard at atonement for one's past crimes.
Fate Stay/Night taught me that people die when they are killed.
Okay so that last one was a bit of a giggle but the point is that anime expanded my horizons and my perceptions of the world far more than any American entertainment did, and I'm better off for it. Yes, anime has a LOT of garbage, but it's sad that the garbage is what gets all of the attention these days.

The lolicon aspect was one thing where it was becoming noticable the worst aspects were really starting to seep into the medium. And even that is getting worse now that last season and the current season has shows where the little girls arent put forward as aggressively sexual, yet it still feels like it is because the main lead practically does not hide their lust, and evem outright states their preference. Wait, nevermind, I actually recall some other recent shows, but still. Their situations are also played like gags, showing that them being arrested is only just a comedic gag.
But it has noticibly gotten worse in the long haul. Modern day isekais are just loaded with problems. The world that they go to isnt important (which kills it fundamentally) and a lot of it involves them dying. Its utterly morbid, they are not interested in getting home because it emphasizes that their life was shit prior to death, and it may as well be akin to 72 virgins type fantasy.
Incest is in your face. Remembet when Oreimo was the leading face? Who knew Pandoras box opened after that hit?
Hell even the rape shit. The fact that Goblin Slayer starts off by going hey Goblins are more clever and will wreck you for being too cocky, and it is ultimately characterized by the rape, both by the audience, as well as author is a fundamental failure on the shows behalf. There was a manga recently called Gal Cleaning which was a wholesome (not really) manga about a dude cleaning a Gals house, and then by chapter 8, it introduces the Student Council President who opposes the two being around each other but secretly she likes the dude. Then then spend a bunch of 8.xx chapters on a flashback on her getting raped by two dudes in a class, and her getting saved by the dude, and now she wants to be "cleaned". And she gets rejected in chapter 9 and the manga ends like 1 or two chapters later. Theres more 8.xx chapters than the main chapter line.
Its ridiculous. I cannot stand that these shows are having an audience that will continue to drag the medium down and cry down any anime that do not have these issues. Its fucking ironic since there were anime that didnt dabble in these more extreme issues up until around Xbox 360 era (which... uugh), but its only now that its a problem to have actual good shit.
