I definitely can't argue with the world's constant decline towards fascism and authoritarianism. Though that doesn't discount the authoritarian tendencies that existed in the Soviet Union that stop it from qualifying as a true democracy.
I think it came closer to democracy as an ideal than any capitalist one tbh, especially before destalinization and the entrenchment of the bureaucracy that came with it.
Also the world isn't sliding toward fascism, that is just the US led imperial core as their power over the rest of the world slips. Plenty of places are freeing themselves right now, look to the west African confederation
