Well, I haven’t seen Naruto, but I have seen the fallacy discussed in relation to Lupin in Harry Potter (werewolf syndrome is pretty similar to HIV/AIDS in terms of how it’s stigmatized, but of course, HIV/AIDS is not actually that dangerous if you take proper precautions with bodily fluids, and it certainly doesn’t cause someone to lose themselves the way werewolves do. HIV/AIDS is an issue I care deeply about when it comes to reducing the stigma around it, because people I care about have it). In Lupin, ghouls, and Eldia, the fallacy presents itself in that all three of these do constitute some degree of a threat (actually, Eldia is the least threatening) whereas real world oppression does not constitute an actual threat besides people desperately clutching their power and security above common sense, decency, and empathy. 

(However, about Eldia, I’ll state that I think the best parallel to be made to the real world is to nuclear weapons, as that seems to be what titans stockpiled in the wall are supposed to represent. It’s almost as if mangas like SnK, TG, and HxH often discuss the concept of nuclear weapons and societal annihilation because, idk, Japan might have a better understanding of that than the rest of the world where certain leaders use nukes to threaten each other whenever they feel like it.)

I think the X-men fallacy is always going to be problematic, and but I also feel like every single story that has ever existed is problematic because the world is filled with different people who have different responses to different experiences. It really depends on what triggers you precisely. I get why people are triggered by certain fallacies and I do not fault them for that, but people have to understand that fiction is not a one-one equivalent for reality, and while you can draw parallels between, say, werewolf syndrome and HIV/AIDS, and between the Holocaust and Eldians, but you also need to understand that that is not necessarily intended to be exactly that. 

I also feel like people need to be able to critically read things. Take the good and leave the parts you don’t like, and acknowledge that nothing is perfect. Like for example, I personally think the armband thing was a bad idea in SnK. We got the point of what was going on in Marlay without that. If it’s too much for someone to handle, that’s fine, but it’s fine for others to enjoy it. 

Of course, I do feel like authors need to be responsible about how these things are handled. If SnK was heading towards a “destroy them they really are evil!” ending (which it is definitely not, even if I don’t expect the majority of our main cast to make it, I do expect freedom for Eldia in the end) that would be irresponsible, 100%. If Lupin ended up going berserk and killing people just because that would have been irresponsible, but his fears of himself were unfounded. 

If people are triggered by SnK or by HP or by X-men, they do not have to read it. Making posts telling others to stop reading it though based on personal feelings, cherry-picking, and saying SnK’s fascist when it’s clearly anti-fascist, is honestly offensive and trivializes something that should not be trivialized.
