That foids are intolerant against non-NT might only be one reason.
The other reason might be that autists instinctively know how attractive they are, and if their goal is to marry, they won't flirt with any foid below their looksmatch (volcel) bc they know they would never marry them bc they logically assume they deserve their looksmatch but they won't get them until late 20s.
Autism is often associated with motoric disorders/etc. that will make you look even more subhuman, you also have certain repetitive behavioral patterns that can be off-putting for women/NORPs (e.g. you creep them out) and when your niche interests (if you have any) are something "socially frowned upon" (like fascism/national socialism/diseases/chemistry/etc.) it's also something that guarantees bullying.
Furthermore it's "funny" for normalfags (and especially for women) to bully someone who is within a certain age range (due to optimism/bluepilled thoughts) not savvy/socially aware enough to recognise it (and even if he recognizes it it's hard to find out which behavior lies behind the constant ridicule).
I always thought as a child that people were interested in what I had to say about various topics or found my jokes funny, in the end I realized that nobody laughed with me and everyone laughed about me.
People also played me like a fiddle due to my pedantism in certain subjects and deliberately triggered me by making mistakes to see me sperg out.
As an autist you move through life without a biological compass that tells others how to navigate through social situations, you constantly find yourself in situations NTs can easily avoid. And sometimes you also piss off others although not wanting it. Autism is a death sentence for sub8 men and even autistic chads/women have it far harder than their NT counterparts (although their struggle is a joke compared to the struggle of an ugly/average autistic male).
And then there is the "positive representation" that led to many believing that autism equals savantism, it doesn't mean that in the slightest, it's most of the time a life long impediment of your personal life - especially when parental pressure associated with a misunderstanding of autism comes into play the whole mixture becomes then even worse because they push you even harder which makes relating to peers even more difficult. You are then almost like a little professor - which means easy prey for bullying. And then there are the older therapeutic methods like attachment therapy or other shit that were still in place a few years ago in some countries and that cause more harm than good.
Trust me I experienced everything of what was written above after getting my Autism diagnosis as a child (to a minor or higher degree). Even now in my 20s I have absolutely no idea about the world or anything because everywhere I went I got dealt a shit hand and even though I was in university it's unlikely that I will get a job without disability programs. Fuck this world.
