Sure, but only if they’re solely in those echo chambers, which if they’re posting in .world, they clearly aren’t.
Not necessarily. Like how people who use 4chan regularly maintain the standards and behaviors even though 4chan isn't their only online community of choice. People take their norms with them, even when they leave home, sort of thing.
And any ones who do are told off because of the content of their posts, not their home servers.
I mean, I agree this should be the case, my point is just that the bad reputation of an .ml home instance is not entirely unearned by the .ml community, regardless of the individual user.
I see quite a few inflammatory posters from .world and .ee (especially of the American exceptionalism, anti-Palestine, and more recently anti-Canadian (🤭) varieties) but I don’t automatically assume every single person on those servers hold those values. In fact, I think 9/10 comments I see you post specifically, PugJ, I agree with.
I can't speak for .ee, but I would point out the same about .world, albeit phrased differently. .world absolutely has a reputation for being more moderate and less leftist than much of the Fediverse (though, again, I would emphasize that 'social democracy' is the standard, and that both North American and European right-wing and center-right parties are reviled, so it's definitely a question of relative political stances), and if you see someone espousing a "Capitalism isn't so bad 🥺" view, the chances of them coming from .world is probably better-than-average, insofar as the Fediverse is concerned. It would not be incorrect to make that connection - pattern recognition is useful.
Remember to treat people as individuals, yes, but when all the [Sportsball Team A] fans are out wearing plain red shirts from [Local Store] for their team, you are not wrong to scrutinize people who choose to wear plain red shirts from [Local Store] extra closely in that light, even if that isn't that individual's intent or leaning.
