That's a more realistic analogy, but my point here isn't that autism is not a multidimensional and continuously distributed trait. My point is only that a spectrum and dichotomized group membership are technically conceivable, even if substantively absurd.
There's a conceivable reality where you have a spectrum of autistic traits, but whether someone is autistic is a strict binary. Imagine a lamp that can have any color, but that is either turned on or off. This would be quite funky, because there'd have to be some sort of mechanism that causes strict grouping - something you see in psychology maybe sometimes in sequence learning research and some types of reasoning research, but otherwise is quite rare.
However, this is obviously not reality.
There's people with more pronounced autistic traits and those with less pronounced ones. There isn't half an autist, but there can be someone whose autistic traits' intensities are near the middle of those of a person who clearly is autistic and those of a person who clearly isn't.
The categorical nature of diagnoses does not reflect the underlying phenomena, it reflects arguments about healthcare resource allocation. The actual phenomena are more nuanced
Narcissism is a somewhat multidimensional trait with gradients of intensity. Who told you that it's a binary classification?

Fewer, not none. Adhd for example tends to interfere with the pursuit of longer term goals in some ways, regardless of society's pressures and expectations. Those make it asymmetrically harder on top of everything else.
The social model of disability is essential, but it's not the only perspective to keep in mind.
Der Schrott wird ueberall reingepresst, ich bins einfach nur leid, den Scheiss ueberall zu sehen.
Don't believe nazi propaganda about those things. They were largely inefficient and disorganized, they just predated others to fuel their goals. It's one of the economic reasons for waging war on everyone: once you use up your local stolen wealth, you gotta raid other people's. Nazi organizational structures were famously broken, with different redundant levels of political control pitted against each other, in line with social darwinist ideas.
And by far not all Nazis were true believers. Tons were "merely" playing along, because they thought they'd get something out of it. They often did, with the wealth of previously Jewish owned (and other) companies being handed to people close to the leadership.
These are parallels, not contrasts.
Oh hey these three (Dawk, Coyne, Pinker) were disappointments/shitty back when the atheism movement of the Aughties split into those who combine it with social justice sentiments and those who just wanna be bigots without also going to church. That tracks.
The GIGO pipeline: Sure, it's garbage, but hear me out! What if we increased the throughput?
