The image attached portrays the defence of Stalin as a waste of time at best, this is frankly charitable compared to most self proclaimed leftists who think the rehabilitation of Stalin is actively harmful towards our movement.
There are reasons as to why the rehabilitation of Stalin is indeed an important issue and not just some trivial thing that we must halt in order to gain a larger following.
The rehabilitation of Stalin's image is less about the rehabilitation of Stalin as a historical individual and more about defending and upholding Marxism.
Condemning or even refusing to uphold Stalin to at least some extent is equivalent to fighting our enemies on their terms. Why would we let our enemies decide who we should love and hate? There's no reason to allow the historical narrative that our enemies have constructed to be our historical narrative, that's just ideological surrender, may as well become a liberal at that point.
The total slander and demonization of Stalin's image is what leads most people into deviationist tendencies, tendencies which are totally harmless towards the bourgeoisie. It's only logical, if people believe Marxism-Leninism led to practically 1984 in real life, then why would they follow it?
Rather than keeping quiet about the USSR under Stalin, it is our duty to defend this period against the reactionary slander laid upon it. It was the first time in human history that mankind entered the socialist mode of production, and that's something to be cherished.
It pains me that people can see that the system lied to us about a great many things, but they still hold fast to the lie of the Red Scare. How can you recognize that they were lying about so many things and believe their other lies? It defies logic. If they lied about one political issue, it stands to reason that they lied about every political issue. The logical response is to throw out everything you've been told and re-examine everything as a whole.
