So citing the research about the causes of autism is now considered “hostility”? Sad. I understand the emotional nature of this topic, but citing the medical research is not displaying hostility towards families of autistic children.

If anything, this is hostility towards those who are, in reality, preying on the emotions of these families for personal financial enrichment. And people who prey on the emotions of others are, imo, worthy of all the hostility they bring upon themselves for their sick, warped motivations.
