Have we learned from our history?

There are those who advocate revolution, at whatever cost, to achieve their self-seeking goals, with the rest of us having little or no insight into what the consequences will be.   In view of supporting revolution, there is no accountability for any extreme radical participation ...the blind analysis is that they are on our side, so that's all that matters.   Then when society falls headlong into a violent lawless state (of no union) ...do we scratch our head, and wonder how we lost so much through the course of demanding our rights ...and living under the pretense that we won?
