FINAL UPDATE
@bdonvr, admin of The Lemmy Club has, in my opinion, responded in good faith to the concerns raised in this post, and so I have withdrawn my proposal for defederation. In summary:
- They will no longer be allowing conservative/right wing communities on their instance
- A couple of accounts were banned ( marathon and Bernard )
- "realcaseyrollins decided to voluntarily close /c/[email protected], /c/[email protected], and /c/[email protected]."
Personally, I think this is just about the ideal outcome, and I hope this will convince folks to give The Lemmy Club another chance.
The Lemmy Club is currently suffering from "The Nazi Bar" problem. All of their top communities are run by three right-wingers as illustrated below.

The Lemmy Club instance admin doesn't seem to want to ban them, for the reasons mentioned below:

This vote is on whether or not we should defederate from this instance until they address their Nazi Bar problem.
Upvote = for defederation.
Downvote = against defederation.
Edit: As others have mentioned, happy to treat this a only a temporary measure until the problem is resolved.
Edit 2: The Lemmy Club admin has said they will implement a rule against right wing communities, and has taken action on some problematic posts and users (see original comments below).

I'm willing to extend the benefit of the doubt to the admin here, as they have responded in good faith:
If you implement those changes then I’d be willing to withdraw the defederation proposal and consider the problem resolved.
Voting against, as I don't believe that jumping directly to talk of defederation is the best option. This stance by OP, along with their suggested method of handling the recent blahaj-related posts to YPTB, gives me pause with regards to their admin status. They have not crossed the line into authoritarian behavior or admin abuse, but it does feel that they are toeing that line.
It is good and justified to spotlight these issues and bring them up for discussion and consensus, which is what OP has done in both cases, but I question the extreme suggestions made in each circumstance.
