Making a fair and accurate statement is not evidence of anti-semitism.
However, if someone uses language to evoke hostility, suspicion, fear, contempt or disgust toward ANY category of human beings — THEN — even a factually true statistical statement can be used for noxious purposes.
There are MANY demographic groups which, historically, have voted predominantly for Republicans or for Democrats OR for right-wing candidates or left-wing candidates.
So what? Why even bring that up unless your purpose is to make some adverse point (perhaps in coded language)
Like the language you've been using regarding the John Birchers? (And, for the record, no I am not now, nor have I ever been, a JBS member).
My attitude is, if something's a true and accurate statement, then it's a true and accurate statement. Period.
