Socialism is uneventful authoritarian? The ideology where power, ownership of production, and wealth is decentralized, removed from the oligarchs and capitalist elite and given back to those who generate it? That’s authoritarian?

I think you, like many who have been subjected to decades of propaganda have equated “socialism” with the failed states that are “communist” in name only, where power and production was centralized to be redistributeto the people, but never followed through with the decentralized part. They’re certainly authoritarian, but they are not socialist.
