Join one of the instances with looser moderation.

Suhh instances tend to be put on shared blocklists, effectively making them echo-chambers too.

I think that says more about the content of those instances being blocked. If you're transmitting content bad enough to get blocked by a large portion of the fediverse, the problem has more to do with what you're saying than their decision not to hear it.

The problem is the assumption that if you allow someone to say something on yur instance, then you necessarily agree with it.
