The point being is are you OK with the government getting your medical information from your doctor without your permission and then making a list for all to see. Sorry I do not trust the government not to fuck it up or use the list for something more nefarious. If they want to make a list of how you are registered to vote, or something else innocuous, that is fine, but my medical information should be between me and my doctor alone. They can still study Autism without naming names.
For a group that notoriously distrusts the government, it's weird you give a former drug addict riddled with brain worms all your trust.
