In 2015 the Supreme Court was 7 Catholics and 2 Jews. 0 Protestants. It’s insane that it worked out like that. Some of it can be explained by demographics I guess, Justices tend to come from the northeast where there are more Catholics and Jews. Even then you’ve still got Clarence Thomas. What proportion of black people from rural Georgia are Catholic, 0.5%?
It hardly matters, but it is quite odd.
TBH I would expect someone's religious views to have a much greater impact on their jurisprudence than their sex or especially skin color. It's kind of shocking how much more attention the latter gets.
