More accurately, we need to hold the leftists accountable for what they have wrought in the name of their ideology. That would require that we indict, try, convict, sentence, and execute the sentence on leftists for giving aid and comfort to the enemy.
Wouldn't the enemy be THEM?
Except, in order to try and execute them, you would first need to wage a civil war.
That is likely something the author would condemn based upon some of his other columns. I'm not sure he would even approve of the trial and execution part let alone a civil war.
Sorry Cal, nobody respects a weakling who is too "civilized" to use force.
