Hmmm.... I think Gothic-Demon definately has an issue, and I think the way you (hong) debunk his trying to express is views is uncalledly harsh.
As for the rules not applying to the DM being a 'bad habit' in your book, in my book this is not a bad habit. IMC the rules DONT apply to the DM. If I want the PC's to meet a firebreathing anti-paladin type with magic resistance, I do not feel the need to have to justify such a foe in terms of classes, templates, prestige classes, feats and other such stuff. It just is the way it is. Deal with it, and move on with the story.
I too get the feeling from reading 3.x rules that there is a tendency to capture everything in rules, sometimes leading to strange situations. I myself prefer to have more DM leeway and have DM's use more common sense and think about stuff themselves. As such I am not saying that 3.x is bad, just that it has a feel like a computer programming set of rules for miniatures/wargamin rather then a guide for DM'ming a story heavy game.
Again, I am not saying that the rules make the other type of play more difficult to do, but more that it IMHO discourages 'common sense'. Naturally in the 'old days' there was a large lack of common sense as well.. This though had also a lot to do with the players themselves being on average less mature as the hobby itself was less mature at the time.
Whether the 'new generations' of players are different, I do not know. Are they different to 'old style' players simply because they are younger? Because they had an upbringing in CRPGs? I don't know. What I DO know, is that the look/feel of the game has changed, and that the rules have tightened. Again, I am not saying that this is bad/worse, but the tightening of rules DOES have impact on the type of game one plays. The games themselves are more codified and more rulesheavy now then before.
As to topics coming back on the boards and 'being old', this is the nature of societal discussion and electronic boards. The wars will never end, deal with it.
