The gun proponents want to believe, and very much want us to believe, that the Jews, if armed, could have prevented the holocaust.
Author Martin Cohen's research documents that well over one and one half million Jews carried weapons and fought against the German military. Author Nechama Tec, in her book "Defiance: The Bielski Partisans", discusses what she calls "the largest armed rescue of Jews by Jews".
Armed Jews did not prevent Hitler from coming into power, nor did armed Jews stop the ensuing genocide we know as The Holocaust. Armed Jews did cause discomfort to the Germans and those countries that allied themselves with Germany.
We need to be significantly more grounded and rely less on suppositions.
