This was the line that baffled me the most ! Was mcvey saying "Jewey" is a very offensive term for a Jew, even in early 1900s, and no Jew would ever stand for it .... and he knows this because he was married to a "Jewess" ??? WTF. Was that some sort of touch of irony or a thought-provoking experiment or something ? Or just mcvey being mcvey? WTF really.
