Where did I say Firefox is bad? Lacking a selling point which distinguish it from competition does not mean it's generally bad, it's just not good enough to bring in enough new users to balance out the loss of users.
I've been seeing this sort of laziness all over lately. Some people seem unable to separate analysis/criticism with opinion on overall worth/merit. i.e. if you think there's anything wrong with Organization X, then you must hate them or secretly be a supporter of Organization Y, their arch nemesis. It's annoying at best, dangerous at worst (because that type of thinking can lead to behavior/decisions that are never questioned or challenged).
