Unfortunately, you probably have a point there.
Bear in mind, of course, when I say "kids", I mostly mean young people in their early teens, i.e., the primary American audience of Naruto and Bleach -- kids that are in the worst position possible to develop a wide range of at least SLIGHTLY more expansive and intellectual tastes in entertainment (I read BOOKS when I was in middle school, I kinda wonder about kids these days). Anime can be intellectually stimulating as well, but these days it's usually tied to more of a social middle/high-school-cliquish angle than anything else, and it becomes more of a collecting hobby than a serious appreciation hobby -- the kids don't really care about the technical merits behind the animation, choreography, etc. of the retarded Bleach fights they're consuming, they just want to gush over the scanslations ASAP so that they can impress their fellow anime dorks. There's no depth to this kind of consumption, and it truly worries me.
That's why I continually root for Avatar to succeed with this demographic -- I figure if kids stop for just a minute to think "whoa whoa whoa, wait a second -- this was made by AMERICANS? But...America is...pig disgusting?", it'll set some gears in motion, and maybe they'll expand their tastes in consumption just a hair, and become stronger, smarter, better nerds for it.
But perhaps that's just the idle roaring of an anime dinosaur...
