What levels of diversity are you expecting? I am here exactly to avoid the extreme polar opposite diversity many mainstream platforms offer. I see people agreeing and disagreeing but they are still having some common ground which enables the disagreement to look civil. Considering the mainstream social media this can look like a lack of diversity, but it’s actually how it is supposed to be in a civilized world…
And also, there’s the platform bias. The fact that you are on Lemmy here and not on Reddit asking this, also gives a lot of information what your opinions are, and by that you already share a lot in common with most people here. Sharing a lot in common also means less things to argue about.
