That’s the mistake most right wing supporters make, they equate socialism with the Russian model of communism, which was not communist in the true sense as Russia never had a communist revolution but a Bolshevik one which evolved into a Stalinist dictatorship.
Lenin was an autocrat who did not abide criticism and the Bolsheviks struggled to retain power after the revolution and in the civil war that followed. What happened then and what is happening even today where left wing politics prevail is that there is constant flux and argument and splits and there is never any periods of consolidation to enable true communism/ socialism ideas to mature and make enough difference in peoples lives.
There was period in the Spanish civil war where true communism began to flourish and many ordinary peasant farmers managed to organise farming co-ops and citizen communes and it was starting to work but the Russian communist party fucked that up by taking over the local militias which resulted in splits and in-fighting which allowed Franco and his right wing allies to crush any real change.
Any one with any rational thought process must believe that capitalism has had it’s day and some other system surely should now be looked at,
