Also I can't stress this enough but he's not really "right about a few things" either.
People's media exposure to RFK is a sanitized version for the most part. He's a lot more nuts than you can imagine even on the things that sound reasonable.

Like take pesticides, he has claimed they cause gender dysphoria.
Or gun violence, he has claimed antidepressants cause mass shootings.
