One of the benefits of a federated social media network is being able to pick an instance that aligns with your own values. If you'd prefer that the admins defederate certain content that isn't defederated by this instance, have you considered using an instance that more closely aligns with your views? As long as they haven't defederated this instance, you'll still be able to interact with any users and communities on this instance that you don't personally block.
I sincerely hope this doesn't sound like I'm asking you to leave. One of the reasons I'm on this instance is that everyone is welcome to make an account, which feels very inclusive to me.
