… with Hitler and Mussolini … on the far right, and Stalin and Lenin on the far left.
Hitler and Mussolini were both socialists (Mussolini was a Communist before going his own way). They departed from Marx over nationalism, not nationalizing farms and industry, and not killing off business/farm owners. Lest you think the latter two significant, business owners and farm owners were kept in place for their business abilities, but made slaves in golden chains. Edit: I forgot! Hitler was infamous for destroying German trade unions; Stalin merely made USSR unions tools of the state; funny thing is, that made little difference to the workers, who were oppressed in Germany and oppressed in the USSR. Oh yeah, Part 2 … when it came to freedom of religion, there was none: not in the USSR; not in Germany. Hitler mainly co-opted religious groups; Stalin was less patient, and sent to the Gulags church leaders who were slow to go with his program.
The conflicts among Stalin, Hitler and Mussolini were over personal power-grabbing and ambition, with their supposed differences being relatively minor and basically pretexts. The realities of common life - working conditions, wages, personal freedoms - and foreign policy were little different between Nazi Germany and Stalinist Russia. Even Hitler’s attempted extermination of Jewish people has a Stalinist parallel.
The Right vs. Left continuum paradigm - Fascism and Communism being the supposed extremes - is an illusion. Reality, IMO (and in others’), is a freedom vs. statism continuum, with anarchy and oligarchic dictatorship (ala Hitler, Stalin, Mussolini, Mao or Kim I, II, & III) being the extreme opposites. And in that freedom vs. statism continuum paradigm, BHO is very much inclined toward statism rather than freedom (though obviously not Stalinist or Hitlerian - no purges, no concentration camps, etc.).
