What you audio snobs fail to grasp is that if loudness somehow wasn't important, it simply wouldn't be happening..
The reason you have to keep explaining is because your "explanation" just doesn't hold water.
The argument you keep going back to is that if it wasn't a good idea, everybody would not be doing it, and the pros would not be for it. As for the first part of it, all one needs to do is step back and look at human nature in the modern world to see that the planet is rife with mass numbers of people, including "the pros", following a bad ideas. The Loudness War has no corner on that market.
As for the pros doing it, look at it close enough and you see that that is a fallacy argument. Ask any engineer or producer what they would do if they wanted to make their stuff any good and not just Big Macs to sell to tweenies, and they HATE the loudness wars. The only MEs who support the Loudness wars are doing so out of self-preservation; because there's a huge market to be seized making a living out of making things louder, all while the "standard model" of mastering for media distribution is disappearing along with the disappearance of CD sales.
And speaking of CD sales, and in fact, sales in general, they've been on a steady decline ever since the latest version of The Wars began, sometime around 1990 or so. The decline started years *before* the Internet became public, so it can't be blamed entirely on the 'net; there was a trend already well in place by then.
And now that most people have managed to fill their iPods and other doohickeys with pretty much all the MP3 replacements of their CDs and albums they want, even e-sales are flattening out or declining (and, no I'm not making that up; there have been whole programs on the radio and TV with the talking head experts talking about this in detail).
Something's gotta change. That's business, if nothing else. And one of the first things that has to change is the general dissatisfaction the buying public (including the kids) with what they perceive to be the quality of music these days. While they may be initially attracted by a nice shiny object like a loud song, it doesn't keep their interest for very long. Song fatigue sets in quickly. Loudness hasn't worked, because the public just is not buying anymore.
So enough of "the pros know what they're doing" argument, because things aren't working any better for them than they are for you and me.
