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admin of The Lemmy Club has, in my opinion, responded in good faith to the concerns raised in this post, and so I have withdrawn my proposal for defederation.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.
They are not being called Nazis, that's just a term used to describe a certain situation. The description links to a definition of it:

Well... it's both. The Nazi Bar analogy, in my mind, is overused for a lot of situations where it doesn't really apply, but in this case it fits extremely well.
And, also, as it happens at least one of them is apparently a literal Nazi.

Yeah, I see that now. When I made that comment there weren't any direct Nazi claims. Yikes.
There we go .
I think that description misses a reason for the problem being the specific tactics and mindset of Nazis and how cultish and exclusionary they are themselves (ie. active contempt for the concept of tolerance). If it was so broad as to mean "people with X opinions/interests are widely disliked, we'll be more popular if we kick them out", to me that seems like a much less reasonable position and a different thing.
