Eehh I kinda disagree. Autism is better to describe my sensory issues and my inability to correctly verbalize what I mean, as well as trouble with facial expressions.
The disorder part is there not only because it makes it harder to interact with people, but because of different information processing (natural or societal). Kinda like how epilepsy is also technically because of difference in information processing.
The conflict isn’t just because neurotypicals made the rules. It’s because they have an easier time forming a set of rules and following them collectively (hence the etymology of the word autism). Different cultures have different rules, and neurotypicals can adjust well. Some people may have subteler difficulties, but even then, it never becomes dehabiliting to a certain point, that point being what is the difference between someone with autism and someone without.
Read a lot, cite sources and explain thouroughly what you think.
I mostly use the last method. Basically, you want to make sure that the other person understands fully what you mean. You can use examples and anecdotes as well.
Training yourself in philosophy also helps, as it makes sure you argument well what you want to say.
