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. 

I struggle with identical things. And I'm not saying you are wrong, just my opinion that is the bowel issues are heightened by stress which is usually societal in its origin, 20 TV channels...is obviously not akin to our natural state... I also struggle with complex tasks, but this is massively amplified by the amount of distractions I face daily.

I suspect, were we to be born into an indigenous tribe in nature somewhere, the things we struggle with in civilisation today, might be of benefit for hunting, tracking, or sensorially beneficial in other ways.

We live in a way that is at odds with how we have evolved. Im sure this sounds a bit far fetched, but I see the abundance of neurodiversity today as being nature's way of redressing the balance that society lacks in the modern world.

But just my view of course
