OH GOD, I didn't mean to write this wall of text, but I already put too much time into writing this so here goes!
Ok, I finally finished watching the video in the OP. I don't want to be vague, but uh, it's kind of unfocused. I learned some interesting things about the social movements in Japan and how what we'd term LGBTQ issues take conceptually different forms. Like x-gender is the equivalent to non-binary, but seems to have it's own connotations due to differences in the culture it emerged from. So, neat, educational, but entirely too and unfocused. Going by the quotes in the OP I figured the video would center more around the anime community and the potential for an Anime Gate, but it only boomerangs back around to the subject at the end. Mostly the video is about how even well intentioned leftists fall into engaging in Orientalism, as do the right, both of which are damaging and ultimately give power to the right-both the MAGA nerds and Japan's right wing party.
I honestly thing this would have been better as a long form essay and while a transcript is on the site linked in the OP, it doesn't read particularly well. So, interesting stuff, could definitely use some editing.
As for my own thoughts on the subject at hand, I am somewhat divided. As an anime fan I can't blame people who look at anime and write it off for being weird and regressive. While there are some that buck the trend, such as last season's excellent Bloom Into You, the shows that seem to catch on in the western community can often have problematic elements such as sexual harassment, voyeurism, pedophilia, and slavery to name but a few. And I specify in the West because, as others have already pointed out, these shows are basically late night commercials for 30 somthing otaku. They're hardly mainstream in Japan. But anime fandom is one of the elements that has shaped portions of western internet culture, probably stemming from 4chan's influence beginning over a decade ago.
So what's popular these days? According to
Crunchyroll last season it was Goblin Slayer. Most streamed new series on Crunchyroll all over the US, parts of Canada, a lot of South America, and Australia. For those who are unfamiliar, much of the controversy surrounds the first episode in which a team of fresh faced adventurers in a vaguely D&D inspried fantasy world are brutally killed and/or raped by goblins which is depicted in graphic detail. There are other issues that crop up as the series goes on such as needing a naked virgin in the same bed as a corpse for the resurrection spell, and goblins using rape victims as human shields. If you're not familiar with the series, at this point you're probably thinking, "What the fuck??? What kind of degenerate anime is this?". Well outside those aforementioned problems it's a mediocre fantasy series about quirky cast of trope laden anime adventurers killing goblins (and sometimes other stuff) or maybe eating some cheese or ice cream. Outside those moments of extremely problematic content it's a middle of the road fantasy adventure.
The problem I see is too many fans (or at least too many vocal fans) outright ignore or try to claim that such content does not exist in the series/isn't that bad/is out of context. It's not. I watched all of Goblin Slayer with my group of anime watching buddies as I'd probably have dropped it otherwise. So here's what I'm putting forward:
1) Criticism of how popular anime handle social issues has merit.
I'm cowardly and I hate calling people out, but I'm going to do it in an oblique and cowardly way regardless to make a point. In this relatively short thread there are already posters saying that anime like Shield Hero don't have problematic elements or people pointing them out weren't interested anyway. It's essentially brushing away criticism by saying those raising the issues weren't interested anyway. That they are missing some sort of essential context. But it's important to understand people consume media differently and have different perspectives. For you, personally, maybe the goblin rape in Ep 1 of Goblin Slayer was a minor footnote and the strengths of the series outweigh that momentary edginess. For me it was a spectre that loomed over the entire series, marring my enjoyment and never completely disappeared. For others it may be so instantly revolting that they drop it right there. So basically what I'm saying is, if you're a fan be honest about the show. Don't try to pretend things that actually occured didn't happen. If someone is concerned about those aspects don't downplay them. Which brings me to...
2) Anime communities need to be more open to criticism and individual anime fans need to be less defensive about said criticism.
This issue exists on ERA in the seasonal anime thread and in this very thread. Being critical of something doesn't mean that thing is entirely without merit. It certainly isn't a personal attack on you. As with many nerd communities anime viewers are seen as often social outcasts. Because of that, when these hobbies expand into other demographics (either intentionally or not) fans become defensive because they feel like other people, perhaps those who once mocked them are now able to partake in
their hobby while still being cool. If you find yourself feeling that way, remember that it isn't rational. These other people just want to enjoy it same as you. They found a show that they connected with on a personal level. It's just the stupid lizard part of your brain trying to create tribal divisions. But even here where we're generally seen as leftist it's sometimes hard to have a proper discussion. And if it's difficult to have a proper discussion here, it can be near impossible in some other online spaces.
3) Anime communities need more left leaning spaces.
This is brought up in the video, but there need to be more left leaning spaces openly discussing and critiquing anime. A few are mentioned in the video.
Anime Feminist has been pretty good for recs and reviews. I'm gonna check out the site mentioned in the OP at length at some later point. We need places to engage in lengthy discussions of these issues without it devolving into shitposting, and hopefully if the leftist anime sphere grows large enough it should shift the nature of anime discourse. But that's probably being a bit too hopeful.
In short, I think part of the solution is anime fans not downplaying problematic aspects found in anime, which leads to better discussion, which improves the outside perception of the anime community. However I don't want to focus too much on the "fix yourselves" aspect as the video in the OP made a valid point that many left leaning, non anime fans unintentionally engage in Orientalism which if you're socially conscious should be something to reflect on.
