I'll settle for "discredited." Equally effective, and much less messy.
‘Discredited’ would be neater and far less messy, no doubt. But history has shown us over and over again that such people won’t just shrug their shoulders and walk away. They believe that their sick dreams or utopia and the power required to make it happen are all the justification they need. They don’t give a rat’s ass what sane people think. Behind their lust for power is a murderous hatred and contempt of humankind. History is my witness.
The only way that the Left will ever “give up” is when we’re all in chains or they’re all dead.
