Yes I have been here for over 2 years, and before we get into it, we must understand where our biases are. When looking at a group the closer they are to you, the more difrent shades you can see. This is why I declared where I was, and why I would consider Lemmygrad more Ideoligistacly open than .World, because when I interact with people from that instance I can see more minor variations.
That being said Lemmy.world when I interact with them, I can play bingo with their answers, and I would say in ideological narrowness it would be either .world or beehaw. Not only this but the Anarchist hub tends to be Hexbear, that being a Left Unity instance, and Anti Leninists, I would like to hear more about this, because I have not heard a Luxemburgist in forever, and while I would love to say I have heard an Orthodox Marxist, most people who self identify like that are merly social democrats. .ML is a generalist instance, and I feel like the hate whip up is far overblown and agian part of my evidence for the ideological narrowness. Is moderation here perfect no, but ML does not ban for being “a liberal” they have a difrent reason behind it. If you want to be banned for being a liberal go to Lemmygrad or Hexbear.
Also I hate to blame it to you, but .world does do the summary banning for “Tanky shit” that is why they decided to without prompting to defederate with lemmygrad, because they could not handle communists existing. This is the reason they preimptivly defederated hexbear before they even joined, and this is the reason they are debating defederating .ML.
We all have biases and it is important to agnoledge them, and what they mean, I am free and open with mine. You have not been for yours.
