Because they shot people who didn't want to be slaves. Why the fuck wouldn't that cause a war with people who refuse to go along? I'm not going to do it. By contrast, I will not shoot you for choosing to starve to death. Be my guest. Don't work. But I will if you try to force me to into slavery. That's the difference. I'm more than happy to let you and the communists voluntarily be communists together. But communism can't exist when people can just choose to leave. That's not communism. It's never voluntary. It will fail if it is and it will fail if it isn't. That's the whole debate here. It's a trash idea and I've said all I have to say on the matter.
