This was surreal to watch: Leftists having an actual argument about ideas! Ninety nine percent of the time they are about pejoratives, ad hominems, misleading non-sequitors, and raw emotional appeals, to the point where engaging in discussion with them is pointless. Of course, it also is possible that the only reason Chris Matthews suddenly decided to tell the truth about his thoughts regarding Socialism is because he has an ulterior motive in wanting to push Bloomberg or Biden.
