A community dedicated to critical left unity and the synthesis of ideas. Everyone is welcome here, but, please avoid uncritical or unproductive sectarianism.
(Please read the rest of their sidebar as well to get a feel)
We as Marxists (regardless of whether ML, trot, Maoist, etc) I believe tend to universally uphold the notion that left-unity is not Marxist. That we practice only Marxist-unity (and with plenty of criticism amongst ourselves at that for non-ML's especially that often goes as far as exclusion for those who don't support AES at least critically).
To put it bluntly: I do not want people who practice left-unity to get a beachhead or toehold here with a dedicated community.
There is an anarchist alternative (raddle), at least one anarchist instance to my recollections on lemmy itself and most liberal and left leaning instances on lemmy allow anarchists but explicitly ban Marxists.
In other words, this is our one, singular space which these people are now pushing into. We should not cede an inch of it to allowing non-Marxists and those who discourage vicious criticism and yes even venting and sneering and meming on of the compatible-left, the CIA-left, the synthetic-left and other such names.
I'll note that hexbear is basically a left unity platform and will be federating with us shortly. They tolerate and allow anarchists and discussion between them and ML's so such content would be better there.
I believe at any rate that anarchists are not disallowed from here if they're here to ask honest questions and not just spew imperialist propaganda and anti-communist, anti-AES dogma. Thus the community serves as nothing more than an attempted safe-space for anarchists and other deviations (left, right, etc), a safe harbor from site rules and standards.
Generally in my experience, younger MLs are welcomed, and questions are answered usually in the manner they are asked. I have seen liberals and anarchists ask questions and or poke around, and so long as no rules are violated, and they are not being disrespectful, they are usually allowed to do so. However we are a marxist, predominantly ML instance, and I find it unwise to make a community that is explicitly for generic left unity, inviting in anarchists and more to the point, disallowing criticism of them as sectarianism.
That's good, allowing discourse on some level is good because otherwise you'll just run into constant witchunts and name-calling over who's saying anarchist things. As long as we're all on the same page and are able to both identify people who are coming here to wreck while also allowing for some fair amount of discourse that's good.
Not that debate is necessarily a good thing, but preventing a "hunt" for wrong think is good at maintaining community cohesion. The trick is finding the balance between what's considered acceptable and what's a sign that someone's acting in bad faith.
This was hexbears approach and for the most part just acting this way led to the site being predominantly ML and the response to vagrant anarchists was usually scaring them away with 40 paragraphs of text.
