Distro wars, like the old vi vs emacs wars (showing my age, I know) is not entirely serious. I never understood sportsball fandom, but it’s kind of like that. Debian is my home team; if you use Fedora, you’re from out-of-town.

Debian unstable doesn’t break all the time, tho. There’s only been a handful of times in my 27 years of using it that something got truly borked.

(That’s not counting times when two packages have the same file and there’s a conflict. That’s trivial to resolve once you’ve seen it a few times. Even that is relatively rare.)
