Feels bad when an awful person makes a great point.
Depends on type of Anarchist, but Hexbear.net, slrpnk.net, and dbzer0 all label themselves as friendly to Anarchists. Some are also on Lemmy.ml, and a few are on Lemmy.world.
That's not my experience. Most people that are genuinely open minded are welcomed, but debatelording and getting emotionally vicious gets banned quickly because Hexbear is for leftists to hang out, not (generally) debating.
Debating in general isn't constructive unless both parties are aligned in goals and seek alignment and alliance.
Lemmy largely has 3 camps, the Anarchists, the Marxists, and the Liberals, and each instance leans overwhelmingly in one or 2 of those directions. Looking at the number of active users on each instance, at this point it's fair to say that the liberal camp is probably the largest, as much as I wish that wasn't true.
That does make for ample radicalization territory, however.
Sometimes I misspell because I use a FOSS keyboard and it doesn't have any tracking or autocorrect, but sometimes I mistype a word regardless and don't go back and read it.
I personally haven't seen any of that while on my Hexbear account, the mods and admins usually do a great job of blocking all of that out.
That's not an accurate way to view Hexbear. Hexbear is very explicitly for Marxists and Anarchists, but the vast majority of users live in areas where those are fringe viewpoints. Hexbear allows people to talk to other like-minded leftists without having to constsntly deal with people hostile to Anarchism and/or Marxism, which is the default in their lives.
A more accurate "bubble" would be instances that uphold ideologies aligned with the status quo in my opinion, as it minimizes exposure to other viewpoints.
That's a bit of an interesting dillema. Anyone that supports something consistently is doing propaganda, so it's generally better if people reveal their biases. As for brigading, it's difficult to tell if there's just a large group of an ideologically different instance coming across a post in their all feed or of its a concerted effort.
I elaborated on my views in my top level comment here, but you can't avoid "censorship." You can only pick which bias you want to see more of. Lemmygrad and Hexbear are more open with their biases, and can be trusted to uphold that bias very reliably. Lemmy.world is more subtle, it focuses on selective defederation and selective removals and bans in order to carefully prune a demographic.
Dbzer0 is interesting, it's mostly tech nerds and those enthusiastic about Anarchism, while remaining federated with Lemmy.world, Hexbear, and Lemmy.ml while defederating from Lemmygrad. As such, it generally leans techy Anarchist with a large influx of Liberals from Lemmy.world and some Marxists from Hexbear on occasion. It isn't as heavy handed with removals as Lemmy.world is in my experience, but it definitely is selective with what the mods and admins consider "acceptable Marxism."
Lemmy.world is incredibly hostile towards Marxists, or anyone too critical of the Democrats or the US' involvement in the genocide of Palestinians. I imagine @ComradeMiao@lemmy.dbzer0.com has similar complaints based off their username.
Wealth concentration was far more equalized in the Soviet system and far more concentrated in the Capitalist system it is today and the Tsarist regime it was before. This wealth was expanded into large safety nets like free healthcare and education, large infrastructure projects like trains, and public housing, as in the Soviet system the Proletariat had control.
It certainly wasn't perfect, but it wasn't Capitalism by any stretch, even during the NEP when there was significant market forces at play. The Soviet economy was based on public ownership and central planning, which are pillars of the Marxian view of Socialism.
Blackshirts and Reds is an excellent critical look at the USSR, where it succeeded and where it failed. If you want something more technical, Is the Red Flag Flying? is a good resource for the depth and foundations of the Soviet Economy.
