It was merely the people who decided they wanted to choose for themselves which doors they would enter, and not be told by an admin they couldn’t enter certain doors.

I don’t like being told which parts of the internet I’m not intelligent enough to decide for myself about how I feel.

and if I see a community on any of them I don’t like, then it’s MY job to block it from my view, not an admins.

I can't see a sensible way to read your comments as anything but critical of admins who choose not to federate with all instances.

My so-called vitriol is because I appreciate that by running an instance, admins are providing a service to me while bearing the brunt of the financial and legal responsibilities that go with that. If I don't like how they run it, it's incumbent on me to get out of their house and move into my own rather than complaining.
