My contention was that they are all radicals. Not that the three are conservative leaning.
The fact that it doesn’t always line up left right doesn’t change the fact that these did.
Unless you consider Gorsuch, Thomas, and Roberts left wing those three cases didn’t. Which I consider you don’t given this comment. 30% of the time opinions are 9-0. If you think most of the cases fit a partisan line go through the cases count how many follow partisan lines. They list them all here.
If you group the justices in two partisan groups Thomas and RBG & Roberts and Sotomayor certainly wouldn’t be on the same sides.
