Prima facie I find it difficult to fathom this level of hostility toward a mediocre rock band - and this is, in fact, what the group in question are: neither among the best nor among the worst in the genre, particularly by comparison to what else was current and on the Homogenized Corporate Radio playlists between 1997 and 2002 or so. I can comprehend being put off and scandalized, perhaps, by mediocrity, having spent seven years studying classical piano; but the hatred - even granting that Suderman is piling on the hyperbole - strikes me as excessive. Seriously, if we're talking about popular acts, past and present, thriving and lingering, there are legions of others far more deserving of detestation. Spice Girls, anyone?
However, at a deeper level, I believe that I do understand at least some of the hostility. That hostility is kindled by earnestness, or the appearance of earnestness, in a culture defined by irony, distance, detachment, self-parody, and cynicism; and the band everyone is hating on was (is?) nothing if not earnest, sincere, in appearance and manner. To be certain, the Jesus Christ poses of Scott Stapp were always tiresome, cloying before the first one even concluded; but even here, the lack of ironic detachment is a factor: Stapp evinced no sense that these were just rock-star-going-through-the-motions-schlock. No, the schlock was genuine.
On the other hand, what our culture does validate, even valorize, is that half-cynical self-distancing that is at once a hallmark of the commodification of culture and all its forms and effects, and the decayed isotope of a richer irony. Sincerity is a sort of personal authenticity and permanence, and what value are these qualities amidst the Hericlitean flux, the maelstrom of chaos and change? Adopt one mask, then discard it, but by all means, do not be seen to be something.
As for the manifestly trashier popular acts that ought to arouse contempt, the reason Serious People tend gaze upon them with amusement, rather than open hatred, probably lies with the perception that the posturing of provocative acts, whether sexual or otherwise, is somehow 'authentic' - which yields the dispiriting conclusion that earnestness, even when largely wholesome and inoffensive, merits contempt, while transgression somehow tells us something important about who we are.
**No, none of the foregoing implies that I think Creed are wonderful. And, buried in the first linked thread is a mention of Jar of Flies, a fine album; indeed, the finest released by Alice in Chains, and far superior to everything Pearl Jam has released since VS. (Rodak, if you're reading, this is for you, in part, since you found it difficult to imagine that any of us would cop to listening to lowbrow material.)
