I think there is something to be said for environmental factors, but probably not in the way you mean.
If it is genetic, and I do think it is, and it's coming down through your parents and grandparents, they grew up with Aspie mentalities, so you would grow up in a home, probably unsuspecting, filled with Aspie mentality. Being in that environment, you're likely to not only be born with your own AS traits, but will also learn some from your parents. Conflicts unique to Aspie-Aspie relationships are bound to crop up, so you're probably very likely to learn certain patterns of action-reaction that are more likely to occur between Aspies, and not so much between non-Aspies. Those patterns could recur throughout your life.
Some of the stuff that you might have learned you can probably overcome. What you'd be left with are the traits that are you and you alone. You can learn to cope with them, but in different ways, usually by "faking it" or pretending you are just like everyone else, but that's just an act.

I'm not likely to be around much longer. As before when I first signed up here years ago, I'm finding that after a long hiatus, and after only a few days back on here, I'm spending way too much time here again already. So I'm requesting my account be locked, banned or whatever. It's just time. Until then, well, I dunno...
