I wonder which one is that group of Zionist users, will have to follow the link to the community you mentioned.
Btw, the small community that defederated feddit.org on this matter is listed in the announcement: https://feddit.org/post/12529640
I am not disingenuous toward the issue, but I might be biased since it's my understanding that Internet always has too many warriors-from-the-sofa. The real issue is with the german law, which might be too restrictive, and that's why I believe your initiative here is welcome.
For the record, I live in Germany, attended demostrations or universities camps in support of Palestine and even there, organizers ask you not to use the phrase "from the river..". That's how f**-up it is. I have seen discussions among the left, some wouldn't show any support for Palestine mostly out of fear (and, sure, ignorance, which in a way would makes you an accomplice to genocide).
It saddens me that people are just looking at the 'overview' (2-3 reports by 1-2 users, here at YTPB, all in a few days) instead of doing their own research. This announcement right here, includes a disingenuous 'tldr' that seems to now be pointing fingers to the instance admins on feddit.org (like, extending the accusations that fell upon c/europe moderation team).
followed the original community (!europe@feddit.org now has a fork under this instance), and I couldn't say they're zionists, nazis or anti-semites. Those who are doing it, stretching these concepts, do it with an agenda (either theirs or 'given')...
