I do happen to listen to a few of the bands you've listed during your rant (Atreyu, Underoath *Pre-They're Only Chasing Safety, Haste the Day), but regardless, I generally listen to music that I can relate to the lyrics. And all the MTV and other mainstream bullshit really does seem to ruin bands that might have been somewhat respectable at one point or another. I do wear band shirts, but only of bands that I actually listen to or used to listen to. I do wear chucks, but only because they're cheap as fuck and have nothing flashy and fancy going on. And I do have my ears stretched to 1/2" because it just kind of got addicting. But judging by your stereotypical rant you'd probably wrongfully categorize me into being one of the scene/emo/hxc homos as well... which is not really the case at all.
I'm not scene by any means, I'm not "hxc" by any means... I'm really just one who couldn't give a shit what others think and one that doesn't look to fads to fit in. I actually tend to just lose interest in whatever I previously had interest in once it does get raped by the scene homos.
Not sure where I'm going with this... but whatever.
Really, theres always going to be the "in" thing and everybody is going to hop on the bandwagon eventually and ruin things for everybody else that has been into whatever is, way before it was considered the "in" thing. The only thing you can do is just wait for the bandwagon to change over and destroy something else instead.
None of that probably had any kind of meaning, and was probably not worth your time to read it if you did (or mine to type it), but meh... oh well, boredom does that.
Heres a similar rant some might like, against the "angst parade" as well.
