I mean, I never called you an ableist bastard. Or even ableist. I just said you were weird, and should probably do some soul searching. I would never psychoanalyse you over your favourite shoe either; shoes are not what I know lol.
What I do know is that, as someone who is autistic, that trying to gatekeep autism is a waste of time. You either catch out the very rare faker, or actively make a hostile space for someone who is earnestly starting to figure out if this is something they are. In my experience, people who do have the hunch they might be autistic... generally are. It's hard to describe to someone who isn't autistic, but it's really hard to convincingly fake a neurological condition. It's a running joke in autistic communities that whenever an undiagnosed friend starts questioning, we give them a peer review lol. If it turns out they aren't, there's a chance they could have some other neurological condition - and all they've done is be incorrect about themselves while they try to figure things out. No harm, no foul.
You are correct that you do need symptoms, but those symptoms are as wildly different as the person who has them. Back to my flawed ice cream bar metaphor, if you get rainbow sprinkles on your ice cream, does everyone get the exact same amount of each colour as you? Well, obviously not. Sprinkles don't work like that. Does that make someone's rainbow sprinkles less "sprinkle-y" because they don't have the exact amount of sprinkles you approve of?
That said, in regards to the claim that you believe cookie8 is accusing you of "talking out your ass" about autism, I do find it peculiar that the self admitted not autistic person is arguing against different autistic people all agreeing your takes/opinions on autism are uninformed at best. This is why I called this the "no true Scotsman" fallacy. You are being faced with autistic people analysing a character through the lens of their lived experience. Instead of either curating your fandom experience to avoid this discussion (the block button is free) or doing some introspection, you are stamping your feet about how the autistic people are wrong, and how you know what real autism is - unlike us wrong autistics.
Anyway, this probably won't do anything for you. Given you've been pitching a fit about how autistic people aren't giving you grace, while you talk down to them about a condition you don't have. Reblog, reply, idc. If you find that certain shoes fit you, maybe don't whine about how everyone is forcing you into the shoe while you place them on your own feet.
