Every social media is collective of thousands of social bubbles.

While I advocating for federated SNS, I personally rarely encounter any toxicity on internet except when I interact with westerner (especially Americans). I carefully choose who I follow and interact, and the algorithm are trained with my interaction to put content that not toxic and relevant to me.

On fediverse alone, I have multiple account that delivers entirely different social experience. My English mastodon.social account that just slightly touch Western politics are thousands times toxic. Even my personal regional political discourse feed on Twitter, Instagram, or Facebook are not as toxic as Western politics on fediverse.
