Not at all and many protestants would diasgree with you. Read "Mein Kampf" and "Hitler's Table Talk" and Luther's "On the Jews and their Lies" and then try and assert that the association is unfair with a straight face.
“I do insist on the certainty that sooner or later—once we hold power—Christianity will be overcome and the German church, without a Pope and without the Bible, and Luther, if he could be with us, would give us his blessing.”
ADOLF HITLER
“Hitler's Speeches”, edited by Professor N. H. Baynes (Oxford, 1942), page 369.
“There is very little to be said for this coarse and foul-mouthed leader of a revolution. It is a real misfortune for humanity that he appeared just at the crisis in the Christian world. Even our burly Defender of the Faith was not a worse man, and did far less mischief. We must hope that the next swing of the pendulum will put an end to Luther's influence in Germany.”
Very Rev. W. R. Inge,(in the Church of England Newspaper”, August 4, 1944).
“It is easy to see how Luther prepared the way for Hitler.”
The late DR. WILLIAM TEMPLE Archbishop of Canterbury (“The Archbishop's Conference, Malvern, London, 1941, page 13).
“Table Talk” was a real eye-opener for me when I was a Lutheran.
That being said: this is Holy Week. I’m not going to bicker with fellow Christians during Holy Week. Luther was an anti-semite and a heretic, but that’s more a German thing than a Lutheran thing. I think it unfair to call Martin Luther “Hitler’s Spiritual Ancestor”; whatever else the arch-heretic was, it is certain that he was no state-worshiper (which is what a fascist is).
