I recommend viewing an instance as someone’s house/home. If you create an account on someone’s instance, you need to abide by their rules, because you are their guest. You can’t go to someone and expect them to tolerate everything you say/do.

If you can’t find an instance that tolerates your views, you should create one which does. That is the great thing about decentralization. If you don’t want to create a home for your views or don’t like decentralization, you should stay on corporate social media, which you can see as a public square. Everyone can join and say what thay want and they only get banned if they get too loud.

The “official” Fediverse is mainly used by a certain type of individuals who hold specific views about love, life and politics. It is not designed to be a public square and it is made easy to filter out opinions you don’t like.

By your other comments I think that you hold conservative values about the world. There are/were instances for conservative opinions, but they don’t/didn’t federate at all. Maybe that’s the reason you can’t find any people supporting your views. Parler.com for example used a Mastodon server as a base for their social media network, but they never enabled federation.

Another example might be gab.com, which is still active and used by many conservative people.
