This.
And also, from what I understand, legit studies that considered ALTERNATE causes (because correlation does not equal causation) found no link between prenatal tylenol usage and autism.
FFS, even shitheels like the Texas Supreme Court have made it clear that scientific opinions that do not eliminate reasonably likely alternate causes are not valid opinions at all.
These people are so desperate to conclude that:
(1) modern medicine in some way is responsible for autism, which totally wasn't a thing before vaccines (even though widespread vaccination pre-dates the significant increase in autism diagnoses) or tylenol or whatever....
That they steadfastly refuse to consider the possibility that:
(2) autism diagnoses began to rise when medicine really started taking it seriously, examining patients for it on ALL spots on the spectrum (that is, the vast majority of diagnoses of autism are on the milder end of the spectrum, so that most folks wouldn't even know the person is "autistic"), and diagnosing it. Thus, there is no material increase in autism, there's just an increase in diagnoses for those reasons.
Nope. It's a crusade, and it will not end until infidels (vaccines, tylenol) are dragged through the street in triumph.
