I have no idea why you think socialism is a totalitarian ideology. Marxism-Leninism certainly is, but there's lots more to socialism than that.
I think I was pretty clear about why. Let me repeat again:
(1) All the forms of socialism I experienced were, in fact, totalitarian.
(2) All the major philosophical and political works advocating socialism (e.g., Marx, Engels, Zinn, etc.) describe a totalitarian ideology, as do the political programs of socialist parties in Democracies.
(3) There are numerous books actually explaining why socialism ends up being (effectively or explicitly) totalitarian (e.g., Hayek, von Mises, Schumpeter).
So far, you haven't been specific about explaining how your ideal form of socialism actually is supposed to operate or what it means. You don't even need to explain this yourself, there are probably thousands of books and hundreds of thousands of papers and essays describing variants of socialism, just pick the one that reflects your views.
Then explain how it deals with the economic calculation problem, how it deals with people who refuse to comply with the economic directives you need to impose in a socialist regime, and what new mechanisms it employs so that people like Stalin, Honecker, Castro, Mao, Ho Chi Minh, Ceausescu, or Tito cannot get into power as they have in other socialist regimes.
