Liberals like to throw around "correlation does not equal causation" when dealing with the correlation between vaccines and autism, but they use this very selectively. It does not apply when they say "vaccines have saved countless lives."
Vaccines have been linked to autism by more than a few studies. Studies discounting this throw out the "Correlation ≠ Causation" or rather study the "rise in belief" of such things and attempt to link it to "conspiracy theory."
