Everyone is entitled to their opinion but the author of the post didn’t write asking what could have caused her child’s autism. She simply stated that he had autism. So bringing up the vaccine issue in this context is totally out of context. Not all parents of autistic kids want to hear the vaccine theory. I respect that some people believe that but maybe it’s the kind of theory best shared among like minded people, not in an environment where many, maybe most people will see it as offensive and as false as the trans identity our children are pursuing.
