Oh, yes -- now his religion was "respectable"! (Because authentic, you see.....)
I once saw a U of Houston history prof deconstructing ethnicity among non-Asian, non-Hispanic, non-Afro-Americans. He was pretty deft, and obviously had had a lot of help cobbling up his toad-in-the-hole of selective reasoning; but basically, "old ethnics" weren't valid anymore because they were too middle-class and had bought into "whiteness". Which sounded hellaciously ascriptive to me and peremptory; but then it's always been a characteristic of the Left, hasn't it, to keep their eye on the Main Enemy while allowing themselves maximum tactical flexibility to achieve their victory?
So you see, "old ethnics bad" and "new ethnics good" -- er, make that "authentic"!
