Newer post-left anarchist who came from anarchist communism. Looking to learn more about primitivism and anti-civ and to clear up misconceptions.

So people at r/Anarchism say things like "Primitivists are fascists and advocate genocide." But what I get out of it is that primmies and anti-civ people don't really advocate that but believe that in the destruction of the state and oppressive economies like capitalism that we wouldn't have the labor of the third world to rely on and so we'd have to give up many luxurious we have now out of necessity. And that huge cities are unsustainable because they have no room to grow their own food and must rely on workers on the outside exploited by capitalism to provide it for them instead of those workers taking care of themselves and their own communities.

Sorry if none of this makes sense, I'm not good at wording my thoughts into words.
