This is misleading at best.
For example: RBG, despite her left-leaning reputation, was easily one of, if not the, most pro-copyright and pro-IP justices on the bench. (Relatedly, she also was pretty pro big business, which rarely fits the portrayed narrative.)
Not all areas of law, especially at the Supreme Court level, easily translate into right/left politics.
