Shut up about the facts, you mean?
Or are you possibly ignorant of the historical connections between islam and nazism? Including the Grand Mufti Haj Amin al-Husseini's participation in the Wannsee conference and the crafting of "the final solution"?
Keep in mind the allies of the German Nazis. The Russians, Japanese, Italians, etc etc. If your not willing to condemn Germany, Italy and Japan at this point, why would you try to connect Islam. It's a waste of time and it generates much more backlash than it moves the argument forward.
