What kind of diversity of thought are you looking for?

Could you give an example?

Is there an intellectually honest point of view that Donald Trump isn’t a fascist?

Small, niche communities, and unfortunately you'll probably need to know what ideas you're interested in ahead of time to get there.

People with intelligent but divergent ideas are always outnumbered by people pushing an agenda, and they end up getting moderated together because it's hard to know the difference, superficially.

Note that it's entirely possible to have an echo chamber that's divergent from bigger echo chambers, and that's were a lot of people are pointing you, because of the instance you asked on.

If by "diverse" you mean "has western conservatives", then considering how the entire concept of the fediverse is progressive, you're not going to find many of them here. On Reddit, there's r/AskPolitics which overall leans liberal and is US centric but is more open to discussion than other subreddits. There's some other debate subreddits as well which you might be interested in. They're helpful for developing political views, but after that hearing the same BS from people who have fundamentally different values gets tiring and people leave so that's why there aren't many of those spaces.

If you're open to other viewpoints that are opposed to both Republican and Democrat, leftist instances like lemmy.ml, Hexbear, Lemmygrad, and dbzer0 have that, and they can have very different stances on other issues as well (i.e. Lemmygrad vs dbzer0). They can still be echo-chambery (which is hard to avoid) but they also tend to have more users that are interested in intellectual debate.

As far as what instance actually has the most diverse points of view, I'd say lemm.ee which federates with basically everybody and I've seen users there from all over the political spectrum. However, there's isn't much in terms of political discussion there compared to other instances.

Imagine your issue with .world being that it's too left-wing

I think Lemmy is at an all-time low for patience towards non-conformist opinions due to recent events being... upsetting. Give it some time and folks will be more willing to consider other ideas i think

Bored of the truth?

No single instance has very "broad" POVs, however some instances are federated more broadly and thus get more points of view. To that end, Lemm.ee and Lemmy.ml are much more diverse than Lemmy.world, which is defederated from the major instances with large populations of Marxists.

Hexbear and Grad tend to have a lot of Marxist (and Anarchist, in the case of Hexbear) perspectives you aren't really seeing much of on Lemmy.world, which is very "US Democrat Liberal."

You aren't going to find anywhere where the virtue of being "different" is worthy of celebration when it comes to POVs, and I think that's a bit of a lost cause. I don't see much value in entertaining the opinions of fascists, as an example.

A better question is which instances have dominant points of view that actually align with the material reality we inhabit. Difference of opinion is only valuable when the opinion is grounded in factual understanding of the real world. It's valuable to have different views and interpretation of the facts, but if a view is divorced from reality then it's just noise.
