The left refuses to live its principles. Instead, it adopts violence and dehumanization as the means they want to use to overcome violence and dehumanization.
"By any means" is the byword of the left, and of all tyrants. This is specifically to include the very acts of grievous evil for which they blame those they oppose. Therein, they bring guns to knife fights. They escalate evil in a specious attempt to overcome evil.
In truth the left does not want to overcome all evil, only the evil it perceives is coming from the right. The left is adamantly in favor of a tyrannical government in which they are in charge.
It will need a transcendent power to overcome the darkness. America will need to willingly embrace God.
