Humor aside, there was nothing particularly Catholic or particularly radical of Sotomayor to have ruled as she has. I am a Presbyterian and I probably would have ruled the same. Indeed most experienced lawyers would recognize it doesn’t even noticeably increase the chances that Sotomayor will rule in their favor when the Supreme Court does rule on the case. It just means that the status quo is preserved until the Supreme Court has a chance to rule, an outcome that is not even very unusual.
But that was enough to reduce her from being a wise latina, to being just another Catholic on a court that is waging a war on women or some silliness. It harkens back to the Know-Nothing party and their paranoid belief that the Irish and German Catholics were some kind of fifth column in America, biding their time until the Pope tells them to overthrow Freedom and Democracy.
