Why is Autism considerd a disorder?

I agree. It should be considered a neurological type only.

The deficits felt come from society being set up for a different neurotype.

Is veganism a disorder?

My more than mild executive functioning deficits(ADHD inattentive type?) have absolutely nothing to do with how society is set up.

I would argue they are problematic because we try to maintain organisation in the modern world. These demands require a lot and offer very little option in succeeding

Me too - no IBS since I retired!

I agree about the bowel issues being stress related, mine went away once I stopped working, but come back occasionally when I have to go somewhere I don't want to go, usually something social that involves a lot of masking, new people and new places. When I'm home, doing things at my pace, I don't have any trouble with this.

In my case none of these are heightened by stress. 
I would have died in nature from not recognising I'm thirsty to the point of passing out from dehydration, or from not recognising I was too hot and getting to shade and getting heat stroke, both of which I have done in the last 3 years. 

It sucks, but it's an innate body issue not a surroundings issue.
