Earlier in this thread I pointed out to you a different study linking genetics to autism, and you were similarly dismissive of it as " stupid." I asked you why you thought it was stupid, and you never replied. Now I finally understand how you were mistaking genetics as applying to immediate families only, instead of broad genetic traits that either arise de novo (as in my citation) or exist worldwide in the human population (as in this case). If you had been more willing to discuss your "rationale" earlier when I had asked, I could have helped you understand the research better and why it was correct, not stupid!
I realize you have explicitedly claimed several times in your threads that you are the smartest person here, but perhaps from time to time the rest of us can offer some new and useful information in areas you may not have studied in detail, such as biology, medicine, history, and physics. I for one am happy to help, particularly because I think many of your fears of vaccines would be resolved if you knew more about the immune system and biology.
