And Madeleine Albright is categorized both as an "American Episcopalian" and a "Czech Jew", the latter claim being tenuous at best, seeing as how she actually started out Roman Catholic.
It's very hard to get rid of these. RfC has been hit with a lot of religious subcategorizations like this, and mostly they've been gotten rid of, except for the Jewish ones which are "ethnic" and thus OK, apparently. We're now having a run of LGBT subcats of the same ilk, and it seems that they may or may not be deleted. At least one doesn't have to look for records about Liberace's parents to categorize him accurately in that regard. Meanwhile Albright is in 20 subject categories, of which seven are these sort of ethnic/religious pride cats. She's also in four college cats.
