Leftist ideology is not a belief system, it is a collection of tactics for grabbing power. There is no point exhausting yourself trying to argue with beliefs that the leftist does not even hold in the first place. When they appear to argue, it is nothing but empty verbiage used as a smoke screen to hide their actions and make their enemies run in circles. A diversion like the hand-waving of an illusionist. The trick is to quickly identify and sabotage their tactics. Leftism is pure tactics, not a belief system. Smash the tactics, and you defeat the left. That is the key insight in dealing with leftists.
