That entire instance is infested with a massive amount of right-wing hate, transphobia, homophobia, and ugly political vitriol under the guise of “allowing free speech”, rising to the same level or worse than lemmygrad (which we have already defederated from for obvious reasons). Please get this garbage off of the “all” page given that the entire instance actively breaks the rules of lemmy.one and is only providing them with a larger platform. I think a few trolls may have already spilled over.
just take a 20 second scroll through this mess or any of the other communities there: https://lemmy.one/c/dankmemes@exploding-heads.com
One important thing to remember is that they were not actually kicked out of any of those platforms, the most extreme communities and people on some platforms were banned but generally the people are still there. And they come out of the woodwork if in any way you or the communities you run are visible in things that they hate.
But the lesson in this is that if those communities are easily findable for less extremist people who might be vulnerable to radicalization the communities will spread. While banning them to more hidden places causes a risk of further and further radicalization inside the group IMO the risk is less than the statistically significant rise of fascism, alt-right and extremist hate that at least Western countries are facing globally. The best way to combat radicalization is also not to let these radicalized communities exist alongside others as they were the same as it gives legitimacy to their viewpoints. And to be honest the best way to combat radicalization is to combat marginalization and suffering by educational measures, accessible mental health support, and robust social security nets that are high enough to actually live and not just survive. But that is not here or there when it comes to talking about internet platforms and their handling of extremist ideology or hate.
I do not personally have as much knowledge of the radicalized left as the radicalized right, different religions, and ethnicities. Partly because as a leftist who is an aid worker focusing on refugees, they don’t tend to come at me in the same way as the constant right-wing extremist viewpoints that come out of windows and doors. But in my opinion same goes for them although I see less of a danger of them becoming statistically significant in the near future. But lets not give them that chance.
Because of my frequent runnings with radicalized rights and the unfortunate need to be also up to date in how radicalization works as refugees can be vulnerable to radicalization, not because of where they are from or what they believe in but because of how they are treated and the conditions they survive in, I really hope we can at least here in Fediverse create a place where the hate while not banned as it is an impossibility is walled well enough that I can feel safe writing this comment. Of course, in this instance I have no real vote as it is not my instance, just giving my few cents.
