I think it is fair to point out that most of Luther's anti-Jew vehemence developed after his health began to fail, and he was in chronic pain.
Also, Luther's anger appears to be 100% ideological, not racial.
Luther held similar views in regard to Muslims, Catholics, and non-Protestant Christian sects.
The ELCA’s present behavior is probably due by far more to draft dodgers who swarmed the seminaries during Vietnam, than any of Herr Luther’s flaws.
