The Luther reference seems gratuitous. It's also a bit of a logical leap. Luther came out of an anti-Semitic organization (see: C-um Nimis Absurdum which also arose out of the same roots). The monk reflected his education and indoctrination in that religious culture.
"Since it is absurd and utterly inconvenient that the Jews, who through their own fault were condemned by God to eternal slavery..." Pope Paul IV
That document first gave us Jewish people being forced to live in ghettos; having to wear yellow marks on their clothing; and their removal from white collar professions. They were forbidden to even eat with "Christians." I feel no strong desire to defend Luther on many points, but to single him out seems odd.
