You are correct sir. People who prefer OS X to KDE will prefer OS X to KDE, and people who prefer KDE to OS X will prefer KDE to OS X. Funny how it works out that way. :)
You made the point I was trying to make far better than I did. Whether or not it's the poster's intent, the terms superior and inferior imply that there is some objective judgement being made about the thing being discussed that is independent of one's personal preferences.
I honestly think that almost all pointless flamewars in tech forums about the relative merits of various languages/operating systems/editors/desktop environments/whatever stem from confusion among the participants over whether personal preferences or objective qualities are being discussed. It doesn't help that for a lot of people in the larval hacker stage, there is no distinction between objective and subjective judgements- if they happen to prefer vi to emacs, they interpret that as meaning that vi is intrinsically better in some way, and isn't just a better fit for their particular workflow or whatever.
