Courage

Edit: Allow me to add a little footnote. Rather than to make light of the image, this image is intended as a humorous salute to the Jew facing down Heinrich Himmler. Where others in the camp are content to simmer and suppress open expression of their resentment, anger, and righteous hate over their circumstances, this man in particular stands up, looks Himmler dead in the eye with a silent challenge to come inside and face him. This man doesn't care if any or none have his back. This man does not care that he is unarmed. He only asks, prays, for a chance at the throat of one of the architects of not just his people's suffering, but all those persecuted by the Nazi regime.

This is what a truly manly man looks like. Not a mustachio'd boxer posing for a picture for a fight promotion. And the caption expresses his attitude as perfectly as anything I've ever seen.
