Is Autism hereditary?

All peer reviewed papers at this point suggest there is the neurotic brain type and the autistic brain type as a generalisation. Both can have added disabilities. There is no such thing as “severe” or “mild” autism. 

in fact, a geneticist I know has said potentially we all hold the autistic DNA just not everyone’s is (lucky enough to be) activated. 

No one should be forced to marry someone they don’t share core values or principles with, and while some of us might be lucky enough to find attraction and similar lifestyles, with out parents who share mutual Trust and Respect, no child will feel grounded. 

A good set of parents who are reasonable, dependable and sound/balanced with their ethics will be able to help a neurotic child not be too oediaplised and resentful or help an autistic child not be too marginalised or clueless. It’s really that simple. 

It's really that simple from our perspective, yes.

Not so simple to those who feel that thousands of years of doing things "their way" has a value and functionality outside of what what we may think works. 

Is our way of selecting a life partner as fulfilling as theirs?

Does ours lead to stable families and good values being passed on to the children?

Arranged or not, shared values is a key ingredient here to the OPs concern for the welfare of the children in a situation where one brain-type might not thrive or be as fluid as the other under ineffective conditions.

I know a few arranged marriages which are proven stable, healthy and lasting. I know a few who found their own spouse and both with children (some Autistic some Allistic) are all thriving for the reasons mentioned.

You're correct - nothing is 'simple'. Perhaps I should've used the word 'fundamental'.
