Hyprland might have some toxic community issues but calling it the project of Nazis is outright disinformation. The guy behind Omarchy is also likely not a Nazi, he might be called right extreme through, certainly anti-Islam and anti-Immigration. Nothing of that bleeds into the Omarchy project which has really nothing to do with politics. Now the question is are you going to support an apolitical project that you like for its merits, if the key person behind it is far right, or do you not?
I can understand both positions but just supporting such a project, doesn't make every supporter a right extreme, let alone a Nazi. That is hyperbole.
