First let's look into the dsm 5 definition

Diagnostic Criteria for 299.00 Autism Spectrum Disorder

To meet diagnostic criteria for ASD according to DSM-5, a child must have persistent deficits in each of three areas of social communication and interaction (see A.1. through A.3. below) plus at least two of four types of restricted, repetitive behaviors (see B.1. through B.4. below).

A Persistent deficits in social communication and social interaction across multiple contexts, as manifested by the following, currently or by history (examples are illustrative, not exhaustive; see text):

1. Deficits in social-emotional reciprocity, ranging, for example, from abnormal social approach and failure of normal back-and-fortconversation; to reduced sharing of interests, emotions, or affect; to failure to initiate or respond to social interactions.
2. Deficits in nonverbal communicative behaviors used for social interaction, ranging, for example, from poorly integrated verbal and nonverbal communication; to abnormalities in eye contact and body
3. language or deficits in understanding and use of gestures; to a total lack of facial expressions and nonverbal communication.
4. Deficits in developing, maintaining, and understand relationships, ranging, for example, from difficulties adjusting behavior to suit various social contexts; to difficulties in sharing imaginative play or in making friends; to absence of interest in peers.

Specify current severity:

Severity is based on social communication impairments and restricted, repetitive patterns of behavior.

B Restricted, repetitive patterns of behavior, interests, or activities, as manifested by at least two of the following, currently or by history (examples are illustrative, not exhaustive; see text):

1. Stereotyped or repetitive motor movements, use of objects, or speech (e.g., simple motor stereotypes, lining up toys or flipping objects, echolalia, idiosyncratic phrases).
2. Insistence on sameness, inflexible adherence to routines, or ritualized patterns of verbal or nonverbal behavior (e.g., extreme distress at small changes, difficulties with transitions, rigid thinking patterns, greeting rituals, need to take same route or eat same food every day).
3. Highly restricted, fixated interests that are abnormal in intensity or focus (e.g., strong attachment to or preoccupation with unusual objects, excessively circumscribed or perseverative interests).
4. Hyper- or hyporeactivity to sensory input or unusual interest in sensory aspects of the environment (e.g. apparent indifference to pain/temperature, adverse response to specific sounds or textures, excessive smelling or touching of objects, visual fascination with lights or movement).

Why this is nonsense

A1 to A3 are vague and these things are not innate things you are born with, it can be due to you not being compatible with the individual you are trying to talk to and being unwilling to fake your personality to get along.

Being good at faking a personality and other social skills is something you can easily learn, being unable to do these things is not something fixed you cannot cure.

Social interactions also depend on factors such as looks and status.

B3 is actually normal human behavior, a lot of people are have highly focused interests like about being very much into a subset of cars or being obsessed with star wars.

B2 is also fairly common, it's just a matter of degree.

What is the actual disability?

Some people diagnosed with autism do suffer from things like sensory overload and mentdows

This is clearly an actual disability but you can get diagnosed with autism even if that doesn't apply to you and this is why i reject the autism label as it's being used today. The issue is lumping together people who are socially nonconformative with people who suffer real disabilities in the same group.

So what's going on here is that when someone struggle socially it is assumed that the individual is mentally ill and then the individual is discarded.

People get labeled as "autistic" by psychiatrist from early age and then they get stigmatized even though there isn't actually anything wrong with them mentally, then they get stigmatized, put in special education and then end up in group homes. It's the act of diagnosing people that causes the harm and not some invisible disorder.
