So from writing later I realized I'm kinda talking about two different communities. It's because I think while Holla Forums hasn't, a culturally similar group that probably contains a fair bit of the people from Holla Forums, but is just a more broad sort of deal, has become the voice or at least a major voice of your ideas.
Anyways.
Honestly no I didn't see it.
But I'm not fully ignorant of the history of that divide within the left, the love and rage collective split over this sort of conflict I think, but when it comes up as a conflict which it has since this place even exists, I think it can be reconciled through similar action to what OP suggested with rephrasing and such, I'm adding on that if you're doing it from a position of being an Holla Forums board (which I assumed he was, simply because that's where this thread is located), there's a lot of baggage that comes from that, we can't go full bat'ko and "take back brocialism", that kind of thing is extremely counter-productive, and I'm not suggesting you would suggest that, but the fact that many many people have praised that idea is kind of a big part of why I think anyone acting from the position of being an Holla Forums board should definitely break those associations. Even refusing to act as an Holla Forums board would be a great example actually, when people act off-site as Holla Forums or as the "alt-left" they're only making things worse.
I think to your three dotted points there, I'd say that it's not so much guilt by association as it is association by association. They legitimately can't tell the difference with a quick glance, the actual reactionaries just appear similar, if people are saying "purge [x] or you are [x]" then they're wrong. I'm saying purge [x] or you will be mistaken for [x], and I think that's what's happening.
I'm not sure if it's directly against a materialist way of thinking, I think again, there's if not an active element, there was at some point, that allowed the stereotype of "class focus = intentionally permitting other issues to get worse" to form. I think that stereotype and that collective belief needs to be broken somehow if you want them to listen to you, which I think you do want.
By this pond I mean, I'm talking about two different communities and I just went up and explained that on top instead of here. So with that, I guess, I would say the people who can't work with others are the ones I am referring mostly to or are the most important here. If your group and their group can work together in a group then there's absolutely no problem from my end, but when people with similar goals can not so much as attempt to reach them together it's a problem for those people.
When I refer to the mainstream left I was talking about the most active and vocal anarchists or marxist groups in the west, not major parties that get more than three votes, just to clear that up to be safe. If a large part of the left shares your views, then you're probably what I mean by mainstream left.
I don't feel like I'm particularly obsessed with them, but I recognize I am practically entirely focused on them, that is because this is an Holla Forums board I just kind of assume that's the main point behind the thread. So while the amount of actual importance is something we could try to find, since there's any in terms of the greater left at all, that means that in terms of itself it's entirely important.
I have to disagree. I think this is a big part of our disagreement too. This board is not one thousand leftists who were always leftists. This board contains people who were convinced by this board. Using culture and fun to spark interest I've put in motion some minor stuff myself in real life. Culture shit has an effect, but, specifically when it comes to distancing yourselves from reactionaries that steal your language it's definitely not that important outside of situations where the left addresses itself, you're fully right there, when it does address itself though and factions within the left are being labelled this and that it seems like it would be important to clear things up for the sake of an effective united force or at least diversion of energy away from self destruction and onto better forms of destruction.
Well. Internally is what I mean.
