Is Frieren autistic?

I dont think those traces even in humans HAVE to mean autism or neurodivergence
being alone, lazy, introvert, bot knowing how to socialize, not understanding or empathizing with others amd not wanting to, not bothering with some things that look super important and not having regularized emotions to transmit are not traits exclusive to someone with autism.
ofc there are lvl to it but autism is more related to how a person perceives the world and how the reality is weirdly diferent for them than to us despite being the same.
autism its more of an error that happens during development and its beyond the persons control, but some ppl chose to have those disfunctional behaviours willingly and have control of it, its just the personality they found. I think its just wrong allways getting to the conclusion that someone has to have X or Y because they decide to act a certain way. Its like when you see an adult women going back and forth frenetically on the bus ehile sitting and you assume she has ADHD when shes rly just lost in tought or felt like doing that.

that out of the way this is anime and shes an elf who lived 1000 yrs, depending on the show 8000 yrs for an elf its middle aged, what for us is "im bored and tired, tomorrow ima sleep till 11am" for her its taking a 3 weeks break of her just doing nothing

Nunca viu uma kuudere antes?
Fora que nem humana ela é, mas mesmo se fosse, personagem humano com essa personalidade é o que mais tem em anime.

Is emotion coming out as crying at a funeral considered odd? And even if all elves (what remains of them) are like her, I think the perspective/angle is still uniquely her's.

If the art IS placing elves as an analog with real world, autistic humans, couldn't the narrative not be ruined and Frieren remain just as interesting?
Couldn't you still remain drawn to watching how one person with autism reacts to others from their unique angle?
People with autism aren't monolithic and the path they walk though life is just as unique as everyone else's. Also, depending on where they are, much like the elves, a person with autism could go a long time without meeting another with autism which would even preserve the uniqueness of that particular attribute to the character throughout their story.

Of course, you should be drawn to whatever aspect of the story and characterization draws you! It just feels as though there's still space to consider the possibility of elves representing a population with such common traits without that being an outright strike against the show.

@Lanyaners would it be bad if elves represented a group of neurodivergent people?

Either the author thinks people with autism give off "having lived for thousands of years" vibes and made it part of their world building for elves to be like that, or she has it, yes.
Personally, I lean towards a very big spoon of: Both, actually.
Its frankly impressive how much it gets worked into nearly every conversation, but I won't waste the effort of listing a ton of examples, mostly because I largely expect this to be read either by hateful weirdos, or people that already agree with me anyway (yes, youre free to respectfully disagree too, I see you) , but safe to say she's one of the most accurately portrayed autistic characters in the medium
