Yes, of course the actual autistic people would know less about how to address their daily issues than doctors /s
Its been shown time and time again though that the people who are gaining attention/views/money on tiktok and whatnot… are not exactly likely to be telling the truth.
People figure out very fast whatever magic flavorful words they need to say every month to farm the clicks and get those likes and shares.
I’d expect the majority of people you see claiming they are autistic on tiktok and proceeding to start giving medical advice about it, are likely just lying for money.
It becomes even more obvious when you look at their history and see that what they focus on shifts every few months in terms of content they push.
