Have any members of the Nazi party under Adolf Hitler (including Hitler) ever been excommunicated from the Catholic Church? I suspect the answer is negative. Hitler was raised Catholic. The Church has from time to time carried out posthumous excommunications, so the idea that it wasn't politically feasible to excommunicate Hitler while he was alive is neither here nor there.

I know the Catholic Church excommunicates Catholics who join Freemasonic lodges, as well as Catholics who the Church judges to be willful heretics. But has the Church ever excommunicated a Catholic purely for being a member of a Communist or National Socialist party? The Church has never excommunicated Adolf Hitler, and some other Catholics who belong to Marxists groups, so I'm curious.
