I believe that it is chemical causing autism and not vaccines. I also believe that autism is a genetic trait derived from the European Neanderthal. As why now more African Americans are getting it than they used to back in the day...reminds me of the Agent Orange controversy. Black people never had this condition prior to the 1970s. It was blamed on the refrigerator [white] moms in the 1950s for not giving their children enough affection. Just like they are saying that ADHD doesn't exist. It is a condition after the fact-when the medication was created BEFORE the actual condition. And we know why....don't we? But!
