As people we like making decisions. We like making choices. It's the illusion of control. We don't have much control over lives so we like it when we have the barest grasps of it.
As an autist. I am somewhat immune from the his illusion because I never had the illusion as NTs do. NTs have control over conversations because they know how to have them. I don't I just follow the motions. They can pick their jobs and their cars. I can't, because being employed is miracle and I can't drive. Even the spouse I picked is out of my hands. Some of us are graceful without having control others like some of the students who have meltdowns because they don't get have the choices they made, are not at all.
Hence the two different camps. Some want cure because they crave the very illusion of control. Some don't because they know there is no such thing as control.
We have little control over our lives and the consequences of said choice. If you believe you're kid is "vaccine damaged" then find some serenity and deal with it. Because you can't fix it. Just as I can't fix the dire fact my husband is leaving with me and going to have to stay with my alcoholic father.
