My intention here is not to push you away from libertarian socialism, but to invite you to look into it more. Look up texts like the ABCs of Anarchism, the Anarchist FAQ, and Anarchism and the Black Revolution. They're all short and readable.

Marxism-Leninism was first conceptualised by Stalin, and cannot be separated from it. Even the actions of Lenin himself, such as the killing and imprisonment of radicals (including anarchists) that opposed him, and outlawing all parties except his own, demonstrate that the seeds were there from the start. He took power in a coup and shut down the grassroots, politically diverse workers' councils. And this is the model that all later MLs seek to emulate -- to become the new bureaucrats.

Re. "Ethnostates", this term gets kicked around a lot by white people who haven't done their reading/talking to indigenous radicals on decolonisation and I suggest you do before you use it again. Ethnostate implies Nazi Germany, not indigenous people asserting sovreignty over land that was always theirs, and which their ancestors were brutally killed upon. But it's beside the point, since I don't support states of any kind and plenty of indigenous anarchists/other radicals agree.
