That's a rather difficult question to answer
While I may not agree with it, there is nothing wrong if the collective population makes the choice to not keep and bear arms (assuming there is not a Constitutional guarantee like the US). The people made the CHOICE (common theme here).
When the socialists took power in Russia and even Germany, no one thought that their rights would be removed, or their arms confiscated so that they could not rise against the tyranny that came later. Those people did not make that choice. A complacency within that society to rely on those goverment hand outs has evoled, and they no longer know any better, self reliance is not comforting to them.
That is why I live here, my grandfather escaped when everything was taken away. The descendants of my relatives that could not escape, they do not know any better, since they have not truly lived in a free society and do not crave freedom.
