The key thing is, sooner or later just like a pond full of toxic mining waste, the toxic waste seeps through and eventually the dams fully break.

We've seen exactly this in politics - it began with Trump and others spreading "birther" conspiracy myths in the Obama time, progressed with the Tea Party and culminated in a full-blown coup attempt where mass casualties were only barely averted.

If you just let a pond of toxic waste accumulate and don't do anything to clean it up, you will inevitably head towards disaster.
