I'm going to paste my comment from a similar topic:

I find that conversation flourishes when you limit it to a certain degree. In spaces which are completely open and have a massive range of opinion, what you’ll find is mostly yelling at each other over broad talking points that everyone is already familiar with. After a while, nothing of interest comes out of the far left clashing with the far right all the time. But when you limit it, time can be spent doing other things than yelling at the dickhead on the other side who you have little to no overlap with and see as a dire enemy. You can talk about nuances in principles, differences in organizing, etc. It makes for richer, more interesting conversation.

There's also quite a huge range within the umbrella of leftism, and honestly we already have a huge enough gap there that there's a lot of worthless clashing. Broadening that would only make the site worse.

Just tell me why lemmy.ml should necessarily be ideologically diverse? To be in permanent chaos and useless fights? I think there is already plenty of such platforms...

>ideologically diverse

Smells like centrism

Because capitalism and other liberal ideologies are inherently exploitative.

very diverse... got communist, anarchist, but everyone speak english

It is mostly communist, and that is very good

Oh, you're a capitalist? Show me your vast swaths of capital then

Ultimately, Lemmy is a Reddit clone and one problem with Reddit-like platforms is the upvote/downvote system heavily promotes groupthink since dissenting opinions are downvoted into oblivion while consensus opinions are promoted. Lemmy attempts to solve this problem by being open source, self-hostable, and federated (which are all great things), but these aspects alone can't totally solve the inherent groupthink problem, it just makes it easier for those with differing views to spin off and start their own instances, which will likely have their own groupthink.

As politically centrist myself, I've basically just unsubscribed from the political communities and focus on the more tech-related ones. If an apolitical or more centrist political Lemmy instance which federated with lemmy.ml was started there's a good chance I'd join.
