Most people don't post into the slop comm thinking it's a containment. They think "I dislike this thing and I want to humiliate it by labeling it slop".
It does not feel like "slop" is a containment comm when it's the 3rd largest comm and growing. It feels like slop is trying to steal the character of chapotraphouse.
The characteristics of Chapo Trap House is a combination of comedy, pop culture, US politics, and US foreign policy. Chapo also had a weekly segment where they would read liberal newspaper opeds and criticize the liberalism.
Marx and Lenin have a considerable amount of writing where they criticize their liberal opponents. When Lenin criticized Kautsky or Bernstein, was it considered slop? No, of course not. In a certain sense, the purpose of left theory is to criticize contradictions and ultimately resolve the contradictions.
I do not mean that more content on hexbear is becoming "slop". I mean that posts which could better fit into other comms are being placed into slop.
We live in a world of contradictions, there are many opposing forces in conflict. The contradictions make people feel uncomfortable and people label those contradictions as slop, but not every contradiction needs to discussed in a containment space.
I agree with your principle of having this comm being a "containment". Then we have to ask, what is being contained? Is the purpose of the slop comm to contain every contradiction? Certainly not, because most of the real world is made up of contradictions.
I would propose that what is contained in a containment comm is the most fringe and socially unacceptable subjects. Things that one would be ashamed to say in public. For example, unhinged social media comments.
The purpose of a containment is to shrink, not grow, and yet slop continues to grow.
Norm Finkelstein is one of the most influential academics of our time. I DO think that Norm should be criticized for his problematic takes. However, I don't think Finkelstein is considered to be slop. I would not be ashamed to speak about Norm Finkelstein in a public space.
What I am saying is that the parameters of slop is too broad.
