While I would not approve of such a registry for its potential for abuse, and least of all under a trump administration, I dont think there is anything to indicate RFK's intent is to eliminate autistic people. His intent is to try to eliminate vaccines, which is equally as idiotic, but when the left needs to frame everything as a nazi extermination camp even when that is obviously not the intent, all it does is weaken any future argument we make.
This kind of way of arguing valid points, but in really idiotic ways is exactly why the right won.
