"There is also the fact that the increase in autism rates directly correlates with the induction of mandatory vaccinations in children.
So the evidence is already very strong for a direct correlation, but who has the money, and is willing, to perform unbiased research to see if this really is the cause?"
Can you believe that the pro-vaccine brigade come out with the "Remember, correlation does not imply causation" line when people say to them what you've just written here? Unbelievably skewed logic and just shows how brain-washed some people are.
Yes, I know what you mean. They are right though that it does not mean causation by itself. But it is a piece of the puzzle. Combine that with the fact that mercury is a known brain toxin and the evidence is even stronger.
