Extremism comes in two flavors, and both are poison. Regardless of flavor, the journey to it is the same. It happens when love for a thing crosses over into hatred for its counterpoint. And where love builds and creates, hatred tears down and destroys.
As such, there is no other possible outcome here besides the two extremes resembling each other more and more. Their goals stretched beyond reformation into dessimation. And ain’t nobody got time for that.
