Honest question: why can’t both communities just exist separately? Isn’t this the magic of the Fediverse?

Your biggest point is that the communities are identical in content and I disagree. Just looking at the top posts of the week, the feddit.uk version has a bunch of memes, while feddid.org seems more news focused. The Fediverse allows us to moderate these communities differently and to have different styles of communities, perfectly shown with this example. They are not identical.

We shouldn’t build up just one community all the time. That just runs into the same problem why people disliked reddit: centralized moderation. It’s not a problem now, but if it ever will be, why can’t there be alternatives. Let’s not try to become the next reddit, but become something better.

Also some people left reddit because it all became to big, they want small groups that actually feel like a community. If people prefer a smaller lemmy community, let them have it. They voted against merging, so let them have it. [email protected] is already linked in their sidebar. Everybody that wants to can switch the community or subscribe to both (which is a possibility!!).

I think you’re in the wrong here, at least on trying to grow the uk community over the org one.

Not that directly, but saying they have “zero worth” might be against GG Article 1

Human dignity is inviolable

Pretty sure dehumanizing can be prosecuted under this, even if its rather tame. Also there have been some laws over the last few years that criminalize violent speech on the internet and that give people the ability to report comments directly to agencies. These might make it quite dangerous for the instance to keep up these comments.

I assure you, German leftist often say way more intense stuff on a daily basis, but not on publicly hosted servers

feddit.org is a German hosted instance that has to abide by the German law. By that law, your comment falls into a grey-zone of legality. As much as I agree with you, they were right in removing your comment, as they are legally obligated to. They could get into trouble if they don’t.

To quote the feddit.org sidebar:

Content that is illegal in Germany, Austria or Switzerland will be deleted and can lead to an immediate ban of the account.
