That being said KDE is better for normal desktop use, which is not in the greatest interest of players right now aside from short netbook boom, which now ended with XP installed on almost all of those small things.
Well especially that Firefox is not a Gnome application and has never had anything to do with Gnome. It's a Mozilla XUL application, which is entirely different from GTK or Gnome or anything else related to Gnome. Same thing with OpenOffice.org, which is not and has never been a GTK or Gnome application.
Oh and FF on linux requires gtk+ and follows gnome HIG ... For me it is an app close to gnome, even if it's XUL deep under the hood. Openoffice has integration packages for both gtk+ and Qt4 so it's a bit different here, or rather it's just as you say in this case
The flaming is because they think that Gnome being popular diminishes KDE. Which is just retarded and is not how the world works. It is not a zero sum game.
