What’s the point of being a socialist dictator for many years/decades if you’re not allowing the people to gain collective control of the land/resources/means of production/etc. for their own benefit?

The point is you’re making that up. Example: USSR.

The USSR reduced inequality to the lowest levels in history, redistributed the land to the peasants from the nobility and the landowners, guaranteed healthcare for everyone for free, free education to the highest level, guaranteed employment and abolished unemployment, guaranteed housing (at an average cost of 3% of monthly income), high quality public transit at affordable prices, heavily subsidized basic foodstuffs, and arguably most importantly, LITERALLY DESTROYED NAZISM saving tens of millions of lives in the process.

Did the system have mistakes? Of course it did, and you won’t find richer criticism than within communist circles, because people actually read about the topic instead of getting our information from the CIA. But despite its flaws, it was still the most liberating and anti-imperialist project in human history, it uplifted hundreds of millions from literal destitute poverty under tsarist autocracy and these people gave themselves all of this progress, importantly, without exploiting the global south.

How can you hate in 2026 the main system that has shown itself capable of facing and destroying fascism?
