Perhaps you need to look at the behaviours of your saviour and his allies since he became Labour party leader, before you discount any possibility he is authoritarian. You need to account for changes to how politicians can act in the modern age compared to the early 1900's.
There is more that can connect Corbyn with Stalin, especially when you account for progression to the modern era of politics and social media. Corbyn can't have MPs locked away or killed for disagreeing with his socialist stance these days, so tactics have changed. But there is plenty of overlapping sentiment if you look at it with pragmatism, rather than blind faith.
As I said, it was tongue in cheek as a true comparison isn't really valid after 8 decades of progression, but to deny any kind of similarity is ignorant.
The idea of "decent socialism" in the further left areas of the Labour party is a farce. I have been at labour party meetings and seen first hand how people with opposing views to Corbyn have been treated.
"Brecht’s communists spent as much time fighting social democrats as Nazis in the 1930s. The Corbynites’ real enemies are not Tories, whom they rather respect for standing up for the interests of their class, but Labour MPs who fail to show the required radical virtue and betray the leftwing cause. They don’t mutter darkly that there will be “no hiding place” for Tory MPs who voted in favour of bombing Isis. They don’t scream that Conservative women are “witches” and “cows”. They don’t deliver death threats to David Cameron.
Their virtuous hatred is righteously reserved for their own side and its ugliness will destroy the myth of leftwing decency more thoroughly than the right ever could."
Owen Smith isn't perfect, but he's the better option for any hope of a proper Opposition to government.
