I re-read the post i quoted, didn't see any reference to positions where RFK Jr moved right.
You now mention national abortion ban, the Kennedys have always professed to be Catholic, the Catholic Church is against abortion so when did he move on this issue.
Against gun control, 2nd ammendment issue, when was he for gun control (against 2nd ammendment) but then moved to opposing gun control (supporting 2nd ammendment)?
Is he anti-vaxer or just against the covid required vaccination? How is this a right vs left issue if its science based? Is for science right wing? But again when did his position change on vaccination?
The right isn't pro Russian so how is this moving right to be for Russian? I'd say is more crazy.
