Congratulations on being an ethnic Jew, but I don't see how that has anything to do with anything.  Your pet theories aside, the fact is that the torture you are referring to stems from insufficient understanding; they think that stuff will help.  The ridicule occurs because we are different; this would occur even if there was no knowledge of autism and increased understanding can only help it.

Furthermore, even you make the argument that it would have been better to stop researching autism in the 70s, this is a moot point.  We didn't, and now there is awareness of it and there are a bunch of harmful quack cures floating around.  Those things will not go away because we ignore them; we need research that proves that they don't work and we need to spread that knowledge around so people will stop using them.

Skateboarding is not a crime.
