Most socialist states have been authoritarian because most of them of were authoritarian before their socialist movements. They are a product of their own cultures. In addition, most are authoritarian because they’re attempting to recreate the successes of the Soviet revolution, and using their system as a baseline.

Also, my first paragraph in that comment was aggressive and I apologize for that. I should have come better than that. But the fact remains, socialism is not the problem. Authoritarianism is. They’re not one and the same, nor is one required for the other.
