John Brown has memorials, it is not like he would not be celebrated. Also, are you trying to claim radical pacifism Because you mentioning John Brown opens interesting questions. At which point is it ok to respond to violence with violence? At which point is it ok to defend others with violence? The time at which he did what he done was already violent and the slavery itself was hold by violence.

Brown claimed that slavery is war (and violence) against own people and therefore it is ok to use violence to fight it. Does the expectation of non-violent opposition holds for anti nazi partisans too? What would be difference? What about other war heroes?
