I beg to differ. I think autistic people have very diverse, usually extreme positions on things. If you're autistic, you may either adopt normie beliefs in their most extreme form, or the opposite, you will get extra black pilled.
I'm on the spectrum and I've been to many neurodiverse discord servers, and even forums online, and I'm telling you many of them hate normies and normie beliefs. But again you can't paint with a broad brush.
For instance, normie feminism: "I believe feminism is good because women are oppressed and deserve respect" bla bla bla. This is the normie version of feminism (you can see why it's wrong).
Autistic feminism: "ALL WOMEN ARE OPPRESSED BY ALL MEN I HATE ALL MEN".
But also autistic beliefs:
"Society is harsh on autistic people."
"Normies/neurotypicals are the origin of evils in this world."
"Autistic foids have it easier than autistic males."
So really, I can't say I agree with you that autistic people in general adopt normie beliefs. But I can confirm that whenever they do adopt a normie belief, they do so in the most extreme manner possible. Autistic liberals are some of the loudest, most obnoxious beings on the planet, for instance.
