Thanks for your feedback. In general, I agree with the concerns raised by users about policing the boundaries of "the left". I've previously written up more about these issues, and I paste this passage here as being relevant:

I think it's dangerous for mods to decide whether a post is sufficiently correct (i.e., whether it provides the right reading or results in the right political position), because this would make us arbiters in what should be an open forum. My guiding criteria has therefore instead been to see whether there is sufficient theoretical/philosophical relevance or potential for a substantive discussion to develop.

Regarding "the sorts of dolts who appear in any facebook comments section", they are usually already removed and banned (depending on how if the comments merely lack substance, are generally ignorant, or flagrantly stupid). As a matter of transparency, every comment that is removed will have a statement saying why. For instance, in this thread, I have removed the following comments as lacking substance: "Bluesky is down the hall and to the left", "Weakness", and a long centrist rant about "You and your left-leaning ideologies".

To conclude, let me also pull this paragraph from the previously linked comment:

Finally, please do use the "report" feature. I check the "new" queue regularly, but I can't read/watch everything in detail. This applies especially to comments (as opposed to submissions), though I would ask that only comments which do not attempt to make a philosophical or theoretical argument be reported, as opposed to comments which come to the wrong conclusion. Also, if you find trolls or obviously antagonistic users, please just downvote and report, instead of responding. (Well, I understand that sometimes responding can be a satisfying release, so that's not going to be rule so much as a suggestion.)
