I have been saying a number of times over the course of my time here, that I think the "echo chamber"-ness of Lemmy is by design.

Each instance is moderated by a different team of people who run their server under a different philosophy. You can see clearly in this thread many from the lemmy.ml instance express mild disdain for "liberals", whereas other instances like lemmy.world and lemm.ee don't hold such animosity to that collective extent, but admins hold other expectations for what should be the norm. The way I view the Fediverse is that it's a collection of echo chambers, which within them help foster discussion between like-minded individuals. However these are networked with each other so you can wander outside that bubble to other instances when you feel like it. You also have control to block groups and instances you don't vibe with.

I know some instance moderation policies remove posts and comments that go far against the grain, but in other instances, unpopular takes just get super downvoted but left for people to see.

I don't consider myself leftist or rightist. I flip both ways on different issues and the middle on other things.

How ever Lemmy is becoming less tolerant of jokes and any view that doesn't line up with a moderator's view on the world.

It took a long time for me to get a ban but it's happened a couple times now.

Admittedly they're from .ml

Though some more left leaning communities have gone full on dog like as though it's Reddit

We shouldn't be encouraging or squelching any political diversity whatsoever, we should be honing in more and more on how things actually are in the world, and the effects things are likely to have, regardless of who it pisses off or pleases.

I’m kind of surprised to see a post like this here, reference most of the many comments. In my experience online discussion trends towards radicalism and it’s not an ideal forum (ha) for reasonable political discussions; for example it’s very simple to demonize something, and with minimal penalty. One thing I can tell you is that there’s plenty of extremism here, and my feed is even spec’d towards memes and to avoid politics. The concentration is aggressive enough that these other perspectives you’re looking for are quickly savaged and oftentimes only expressed by people who aren’t smart in picking their fights and it shows in their viewpoints too. No idea how one would address that, like I said I think online forums are probably not the right tool for this sort of thing. Idk man, I just want my memes and hobby info without watching people seethe about American politics and wish for the murder of rich people in almost every community, political or not

The size of my block list tells me there are plenty of right-wing voices on the platform. No everyone on that list is right-wing, but I'm fairly certain a majority of them are.
