I understand (but will stand corrected by Americans on here) that a 'proper' American used to be a WASP, ie, White Anglo-Saxon Protestant, the election of JFK as president was a big deal because he was a Catholic. The fact that a Catholic like Vance is in the vanguard of American nationalism shows how things have changed*
The Supreme Court is stuffed (over half) with Catholics and it's clearly been a deliberate thing. Scary if you think women's rights are important.
