In the 40's and 50's when autism was more rare the common stereotype was to blame it on cold or masculine mothers.
I think there is an element of truth to that.
Also I agree that the parents, especially unhealthy mothers, are partialyl to blame. Worm infested unhealthy women who have no place bearing children, and who are probably inches away themselves from autistic disorders suddenly act surprised when their offspring pop out defective.
The rest of it is metals and diet.
The way things are going autists will outnumber everyone else.
Can you imgagine the trauma a fetus must endure growing in a sac either filled with worms or right next door to them.
And then these insane women and the new social organizations they create have the audacity to call their kids indigo children as if being poisoned from birth, damaged, and socially outcase was an honor.
