I mean, you used that reference because you are implying that shutting down those pro-capitalist counter-revolutions by literal fascists using force was a bad thing, that's why you said "leftists supporting authoritarianism while claiming to be leftist".
You're just demonstrating that you have never actually engaged with learning about any of these events. You have the vagueist knowledge about them and only understand them within the lens of "tankies bad" instead of what actually happened during those events, why certain decisions were made, and what we have learned in the decades since they occurred that proved the supporters to be on the right side of the decisions.
