If some people say the #fediverse is a left-progressive project, it only shows how successful we collectively are to block the Nazis. Loads of far-right instances and users exist in the fediverse. Gab, anyone? But defederation and blocking makes that part invisible to most of us. They still exist and federate amongst themselves. ActivityPub, the protocol, is neutral. We decide what we want and not want. The fediverse is a herd of Venn diagrams, not a closed circle.
