I am an American by birth, my grandparents German immigrants, they have no guilt for the actions of Nazi Germany, and the Germans born since the war don't either. Americans as a rule don't buy the idea that a race is guilty of the sins of a member of that race. Some do, they are Progressive/Democrats they usually aren't on this board.
As far as The Jews and Their Lies not being in Lutheran curricula, why should it be. It isn't taught or professed. Unless you are the Highlander you weren't around when it was written, but you are choosing to be offended by it. Your right as a citizen at least for the present, but put away your tar brush.
The arrow-shooter does have a small point to make. The Bible is an extremely candid book. When people from Abraham forward (the line of faith from which Judaism and Christianity both sprang) screwed up... there it is. In black and white. The glory is clearly going to God, who is persisting in every effort to bless a stubborn mankind. And teaching the truth that Luther also made bad mistakes would be in that very tradition. One doesn’t have to wallow in those sordid works to acknowledge that it was there. The truth of Christian worship as understood by Lutherans doesn’t depend on Martin Luther having been some kind of perfect angel, any more than the faith of Abraham depends on Abraham not having lain with Hagar (we can thank that for today’s rabid Islamic Arabs, which do far more damage than Christendom ever did in its worst hours).
