It’s the age old staple of antisemitic thinking: the idea that he is in a morally superior position to dictate to Jews the best way to be Jewish, or else… The coercion and barely-concealed threat implicit in this statement reminds me of the medieval custom much favoured by mendicant priests, to force themselves and their homilies upon Jews in the synagogues. Dominican and Franciscan preachers regularly compelled Jews to listen to their preaching, ofter securing royal sanction to invade Sabbath synagogue services for that purpose. Usually, also, accompanied by an angry Christian mob.
