> Now, when you raise a kid it's easier to understand what's happening when she/he has the same kind of behaviors, physical type (including heredital illnesses) as you.

I feel this is a very important concept.

I have some personal experience with aspergers and ASD, and have learned a great deal about how such people look at the world and how that differs from those more neurally typical.

I intend to have children, but I would seriously reconsider bringing someone with my genes into the world without the benefit of my experienced guidance. I would be able to teach them so much that other parents would not even realize they needed to learn. Borderline cases in particular can leave people relatively normal in appearance (although no one who knew me ever called me normal) but completely blind to so much that they need to be able to see to function successfully in the world.

I know it well because there was so much that nobody realized that I needed to learn, and so much needless suffering that I now know is largely preventable. An aware parent with your own genes is irreplaceable.
