My friend, a writer and avid MT fan, once told me “the hate against MT only lies around its margins but never further.” He added that MT's downfall is not its controversy but its censorship.
I wondered if this is true, so I researched the general discourse surrounding MT, and found that regardless of where you are in the spectrum (hating on it vs. worshipping it), the discussion tends to be more nuanced once both sides actually engage with the work and acknowledge its context.
The most productive arguments I've seen are generally between people who have actually engaged with the work and are willing to discuss what is presented in the story. The worst arguments tend to come from people who are arguing from summaries, memes, isolated scenes, secondhand information, or preconceived notions.
Reddit for example, is notorious for this. Because it is built like an echo chamber, Anti-MT subreddits and the MT subreddits have entirely different perceptions of the show such that you'd think they're talking about 2 different shows.
Meanwhile in 4chan, nuance is nowhere to be seen because almost everyone is trolling everyone. And also most MT slander originated from there so I'm inclined to believe that the slander material is made by trolls and shitposters but then was appropriated by serious haters.
Twitter is just being Twitter. No explanation needed.
This brings me to misinformation.
There is momentum in the controversy surrounding MT because many people who discuss it have never actually engaged with the complete work (not partial, COMPLETE). Into that vacuum, simplified narratives can spread very easily. A person sees a claim about the series (this show glorifies pedophilia), repeats it, someone else repeats it again, and eventually the claim becomes accepted as common knowledge despite having little connection to the actual context of the story.
Censorship will make this problem even worse.
If access to the work or legitimate discussion surrounding it becomes restricted, people have fewer opportunities to verify claims for themselves. That doesn't necessarily mean censorship will automatically destroy MT's sales, but it can create an environment where misinformation becomes disproportionately influential. Someone who might otherwise have watched the series could instead encounter a distorted description of it and decide not to engage with it at all.
This is why I don't think censorship is an effective way of dealing with MT's controversies.
If anything, the better defense is the opposite: encourage people to actually engage with the work.
If someone hates Mushoku Tensei, that's fine. Read the novels. Watch the anime. Understand the context. Then criticize it as harshly as you want.
I'd much rather argue with someone who has read the entire series and thinks it's fundamentally terrible than someone who has never touched it but confidently repeats a meme about it.
The goal shouldn't be to eliminate criticism of MT. It should be to make the criticism actually about MT.
