I have no problem with people disagreeing. It's the bitching and name calling that ticks me off. If their vision does not fit yours (people in general, not you in particular) then switch to something else. I was a hardcore Ubuntu-user for quite a few years. But since I felt they were going in the wrong direction, I switched to Fedora a few releases ago. And that was the end of that.
Likewise. There's nothing wrong with disagreeing with the Gnome guys, but the amount of nastiness and abuse directed their way is really depressing.
