You said the “basis” aka the origin of something.
By basis I mean the foundamental principles.
But regardless, you claim to be a leftist and have not read a single theory? Lol
I do things differently. Instead of reading theories about leftism, I surround myself by those who I feel are the most coherent, human, optimist and more grounded into our reality, here, Leftists, communists, sometimes anarchist, artist and scientists.
Only when I'm ready to read and learn about a concept I start reading and seeking knowledge about it. The road to real leftism is slow, at least for me.
Communism is socialism the same way a square is a rectangle. Marx used those terms interchangeably.
PErhaps, but Marx doesn't live in our timeline right now. And right now, communism and socialism are two very different things. You can't always use old windows to look at the present reality. You need to adapt the instrument of mesure.
Communism combining with the state is more of a Marxist Leninist thing. Unless you think that is the true form of communism a commune can pretty much be communist
I don't have enough knowledge to reply to this. All I can say is the logical thing: If you build a commune, then the commune becomes the system.
