Yeah, I’ve always wondered that myself. For instance, my family is lapsed Galicianer Belzer Chassidim. (We discontinued our affiliation about 90 years ago, so don’t say anything, please.) We live a pretty yeshivish life, and we’re always classified as Litvish for some reason I don’t understand, though none of my ancestors ever lived in Lithuania or had Lithuanian minhagim (my great-grandfather pretended he was Litvish, but that’s another story).
Just to add a bit more to the discussion, what in YOUR opinion is the definition of chareidi? It’s one of those things I’ve never understood.
