Confronted by State, police, and army, the armed militias of the Communists & Social Democrats had no choice. (The non-Nazi conservative militia subordinated itself to the Nazis quite quickly.) 
So how was this supposed to work for Germany's 430,000 Jews, mostly middle class property-owners and professionals? Were they supposed to organize their own mini-Haganah to battle in the streets in 1932? A battle that the Communists & Socialists had already lost?
Or were these Jewish middle class professionals one by one supposed to fetch their Mausers from the basement and battle the police and army like so many Herr Professor Cliven Bundys? How long would Cliven Bundy have lasted against the Gestapo & Wehrmacht?
Or maybe you mean: what was needed in 1932-33 was hundreds of thousands of Jews with guns - and not only guns, but also the full spectrum of military technology, under trained leadership, subject to political authority? Congratulations - you've just described Zionism!
But even a state of your own was no ultimate guarantee. The Czechs and Slovaks had a state. The Poles had a state. The French had a state - and a Maginot Line too.
I won't extend this. I only ask: if you invoke the victims of Nazism - non-Jewish as well as Jewish - have enough respect to study a little what they were up against, before retrospectively scolding them for failing to defeat the most lethal state project in European history
