Nah, autistic people can be and are very intelligent, don't let his complete cruelty and stupidity hide behind a diagnosis.

Also retarded is mostly used as a slur meant to insult the intelligence of people by making a connection between lack of intelligence and developmental disabilities. The difference between the two is that developmental disabilities can cause lower intelligence but are actually mostly comprised of aspects not directly related to intelligence, such as not understanding or naturally picking up social cues, sensory issues that overwhelm the vrain making it hard to actually think properly (Imagine being stabbed, you would also have a hard time acting "normal" or intellectual at that moment) etc.

Fuck elon, his fucked up words and actions cannot and should not be dismissed as any thing related to autism.
