The Left is obviously in panic mode. They KNOW that they are being shown for the shallow, sad examples of human failure that they are. Their only option now is to LIE and to engage in the ad hominem attack since their argument has totally collapsed. This is why they call anyone who opposes their agenda as “racist,” “reactionary,” etc. The Left has very much in common with the totalitarian regimes that have littered history (N Korea, China, Nazi Germany, USSR, Cuba). They have zero credibility so they lash out with ad hominem attacks (in Latin “attack the man”).
I teach rhetoric and argumentation at a college, by the way, so I have a little knowledge in this area. I would mark the Left’s “paper” with a “NG” or an “F” for not following proper argumentation. The ad hominem attack is defined as a logical fallacy. Essentially it shows that you HAVE LOST YOUR ARGUMENT and are flinging whatever rhetorical feces you can extrude at your opponent who (typically) is kicking your ass.
