"A system proven to kill millions is a bad system. That is true if it is 1 million or 2.5 million. Again I would point out that you should blame individual actors for their atrocities, not the tools they used to carry their deeds out."
If the system is what enables them to kill millions anybody fighting to uphold the system should be slaughtered. Again, capitalism can not exist without imperialism, it doesn't matter who is in charge.
So all communists, all capitalists, and anyone supporting either should be slaughtered? Who does that leave alive?
who does that leave alive? Those who support the system that promoted the most life, the one that hasn't killed hundreds of millions due to poverty, the one that hasn't killed hundreds of millions in war, and the one where the people are free to choose their own life.
The Communists would still be alive. To my knowledge the mutualists would be alive and so would many other form of anarchists.
In fact the only ones dying would be those who try to stop the transition to one of those systems.
