I believe in socialism, but I feel Stalin shouldn't be idolised due to things like the Gulag.
I would like more people to become socialist, but I feel not condemning Stalin doesn't help the cause.
I've tried to have a constructieve conversation about this, but I basically get angry comments calling me stupid for believing he did atrocious things.
That's not how you win someone over.
I struggle to believe the Gulag etc. Never happened, and if it happened I firmly believe Stalin should be condemned.
Regarding Lenin, he specifically had beef with Stalin over his rude treatment of Lenin's wife, and wished someone would replace him who was in all manner the same except kinder. Ie, Lenin fully backed Stalin's positions, theoretical understanding, etc and wished he was simply a kinder person towards comrades when interacting with them.
Stalin tried to resign over this, and his resignation was rejected.
For further reading: Archival evidence and records show he tried to resign no fewer than four times, all rejected.
