Oh yea, I'd never question anyone having a hard time. In the context of the meme specifically it doesn't make much sense to question things, now that I think about it. If only autistic people go "yea sounds about right" there's a good chance you're autistic anyway.
But I've seen it personally where ppl match some symptoms and become utterly convinced they must have a specific disorder, and it doesn't make sense either. There's no huge harm to it but esp an awareness of differential diagnosis seems to be lacking.
