Liberalism and Conservatism are dead.  The Authoritarians took them behind the barn and shot both of them.

For all intents and purposes the Democratic and Republican parties are dead too.  The Democrats have failed their base for so long they don't really have one anymore and Republicans know they only win in red districts because of the greed, ignorance, and/or arrogance of their constituents, like MAGA cult members.

As my drafting teacher in Jr. High School used to say about disagreeable people, "They too will soon die and pass from the scene."  Farewell David Horowitz, sorry you had to stay so long.
