Off the cuff, AS wrote something poorly enough that it looks like Jew baiting (of the old-fashioned 'meddlesome Jew!' variety); and rather than acknowledge it to move on, AS is digging in, after having pointed out, with a tinge of libel stirred in, that Leon is no better [and probably worse], with his gay-slur and outsized "undialectical bit".
Did you get all that?
I know, I know .. life is too short.
