Ymribiat”Those types of registries are handy references for Natzi’s, mullahs, and LDS”
That was always what came to mind whenever I hear of shul membership lists and the like. Since that’s what was used to round up Jews in the past. The difference is though that nowaDays they don’t really need lists since the government, Google, and every app you sign up for know everything about everyone including all document numbers and photos. But it’s just the thought that makes it uncomfortable.
