Millions of Jews who refused to renounce or lie about their faith who died at the hands of the Nazis are not "martyrs"?
The author's point was the Jews had no choice in the matter, their fate was sealed. JWs on the other hand did have a choice. They could save themselves by bowing down and worshiping Hitler, something they largely refused to do and something that cannot be said of most mainstream Christians in Weimar Germany, or the Third Reich.
I won’t respond further to slander and deliberate misquotes.
