Fact is it's quasi impossible not to have either on any forums dabbling into politic topics in current day. Precisely because of what you call "dog whistles" (by definition a sound most people can't hear) and "nazi adjacent" (by definition you can't be both "'adjacent" to a thing and be that thing, so using this term means advocating banning non-nazis people subjectively considered as "adjacent" to them).
If a forum tries to ban what some people will identify as "dog whistles" or "nazi adjacent", the only effect would be to make alt-right types use more subtile "dog whistles", making them look a bit less "nazi adjacent", then the forum has to ban them too, and the story repeats itself endlessly, with more and more innocent being confused with the actual propagandists (as they don't hear, and so use the whistle), up to turning a place into resetera. And it's same in the larger society, look at what happen to the poor people that haven't realised the "new meaning" of the ok sign for example and lost jobs because of that. It's actually the real goal of the alt-right, riling up the left until it behaves totalitarian, and then exploiting all the people pissed by that / turn false positives into new militants.
Resetera style moderation serves the alt-right more than it really threatens it.
Personnally clown world also made me hesitate to join this place as it's such a textbook illustration of the main alt-right tactic as described in innuendo videos etc... (taking ultra extreme examples of "sjw" or sexual minorities activists behavior, making people laugh about them in what may first look like as innocent jokes, and then slowing moving the goal post into assimilating the whole left to them or adding other far right propaganda in the mix - like extreme drama about the immigration in Europe turning our countries into complete hellholes, something that always makes me laugh as a french - climate denialism or references to conspiracy theories) it can only make any non far-right people with some political culture suspicious.
But on the other hand what would be the best to avoid things like clown world existing ? Censoring speech (with affermentionned escalation effect) or actually having "sjw" types and representants of protected groups stop ridiculing the left with regularly insane behavior some in the left then feel forced to defend, even if they mock it in private, just because of their identity. What % of the behaviors mocked in clown world aren't really ridiculous and condemnable even in the interest of the left itself ? Isn't the threat of helping the alt-right discourse actually a chance for the left to actually realize what cuts it from the average people ? Personnally the more I think about it, the more I consider this kind of topic actually usefull, there's a virtue in being mocked when it's desserved, and not only letting this discourse exist but actually listening to it may be the main hope for the left to evolve and one day speaks to the 99% (or the 89-% as there are easily 10% of insane people, including not only the nazis but a worrying quantity in the left, that should be considered lost to science and would be better ignored/fought than catered to, something this kind of thread helps realise).
Anyway even their right to speak (as opposed to what they actually say) should be defended when it's simply speech (not open calls to violence) , as it's impossible to both support free speech without allowing people express point of views you consider disastrously wrong. And there's no democracy without as large possible freedom to speak (I know I'm not in complete agreement with both my country and some part of the modern left on that).
ps : sorry for another serious and political post from a reeefugee only posting in this thread
. Came here just to make fun or rera originally, but as that thread took a different direction...
