Memes

You're combining disparate groups of people using arguments against things they aren't bringing up, and deliberately missing the points brought up.

The people who tell you that the USSR wasn't true Communism are correct, it never reached there. By deliberately using wrong terminology, you prove a lack of intention to actually talk to Socialists. Don't say "Communism failed," say that Socialist countries have failed to react Communism. Then you may have an actual convo. People don't usually reject the USSR being Socialist, they just point out how you're using wrong terminology, correctly.

Additionally, it is absolutely not the same to say Capitalism inevitably fails. The people who say that do so by analyzing the mechanics of Capitalism, not by vaguely gesturing at fallen Capitalist states and assuming means from ends to fit their narrative. Analyze the fall of the USSR, there's a ton that went wrong that can be learned from, but none of it was because tools turn people evil if they collectively own them. There's no mysticism to tools, people can collectively own them without issue, it's all a matter of how. Worker co-operatives prove this, they are more stable and have higher rates of employee satisfaction. Same with public programs like single payer Healthcare, or housing initiatives like in Red Vienna.

Finally, for this meme. The Conquest of Bread is a book by Anarcho-Communist Pyotr Kropotkin. The image is a well-known and widely-shared meme, with the Hammer and Sickle all, but the changes made by OP indicate this is supposed to be from an Anarchist perspective, not Marxist-Leninist like the USSR. You're arguing against ghosts that aren't here.

Please, if you want to say anything of value, start by using correct terminology. You'll get farther.
