why one would deliberately praise any authoritarian system this hard.
To quote Bertrand Russell: "Much that passes as idealism is disguised hatred or disguised love of power."
To put it simply, a lot of tankies crave power but just don't want to admit. They are simply faux concerning for their own ulterior motive. I saw a meme from one of the .ml instances stating that communism simply "wants to improve" society. But I was like: didn't you guys suppress free elections and speech and persecuted anyone who simply disagrees at the slightest?
It's not uncommon for many authoritarian communists to eventually become fascists, especially after the end of the Cold War. The ex-leader of Red Army faction became neo-fascist in 2000s. A local politician in my country ran on xenophobic platform, but was a member of a Marxist-Leninist party in the 1970s. All that said, it means these people simply run on whatever ideologies, so long as they can attain power for power's sake.
