The reaction is funny too, because in my experience comparing communities of various distros, Fedora's community is among the the most inviting and professionally-behaving of them.

Personally, I am not running Fedora at the moment, but probably will when my Framework 16 arrives, since Fedora is officially supported on it. And to be honest, I find that I am making the same choices with Arch as Fedora would have made for me (aside from bootloader), so I feel that I'm wasting a bit of effort.
