Ah yes, you also said you need a central party control for socialism.
You said they had socialism, I said they didn’t. You didn’t prove anything. If you wanna go into how elections were run and how candidates were chosen then we can but the picture you provided was accurate for just a brief period in the USSR. I can’t remember if worker councils were dismantled during Lenin or Stalin but by the time they occupied Estonia they weren’t a thing. In the USSR the higher ups in the party controlled the means of production, they also controlled who people can vote for while making sure that vote didn’t change anything.
