I get your point. Trying to categorize people does create more division.

But we’re not talking about eugenics. We’re talking about treatment.

I wasn’t bringing up the eugenics roots of “high function/low functioning” to call gene therapy eugenics, I did it to reject the idea that these people in your hypothetical are of less value if they don’t take the gene therapy. When we say that autism is not a disease, we mean that it is that autistic people have material needs to be met, just like anyone else, and the autism itself is not a problem.

Also,

Do you have the same opinion for someone with a level 3 on the ASD? They will require constant care just to function, and will decrease the material conditions of anyone who takes care of them.

From each according to their ability, to each according to their need, unless we’re talking about autism, in which it’s better to purge their genes of neurodivergence than ask anyone to help them out, apparently
