Ah, I see. Well, first of all, if it's just a friendly debate, I doubt you would get banned from this forum. Heck, I think you and I are the only ones in here.
From what I gather, you're saying that the Japanese style of comic-book drawing (manga... but e'ry one knows that) has grabbed "youthful minds" from the stalk, not unlike a young sapling being torn from its birthplace. Continuing with the sapling analogy, you fear that this young sapling would be grown in a pot, all cramped and stuff, unable to grow to its true self. Horrors indeed! If that were the case.
I agree that if you adopt a popular style and define your art around it, your art will just be... part of a popular style. Art should be ever-evolving; from the cave paintings in Lascal to the wall paintings depicting ancient pharoahs to the life-like yet unexpressive Greek sculpture and eventually to our own art. It would be pretty suck-ass if we still drew like Egyptians. Boring fight scenes, yeah?
But the "youthful minds" are only taking this popular culture of Japanese art and taking it as their own to use as a springboard to create their own style. They just need a boost. I ,myself, am guilty of this; my style is heavily influenced by the Japanese style. I could have chosen to do my comic with a Mike Turner influence (Witchblade or Fathom... damn that guy can draw a chick) but I felt my story would be better told through a style that was a bit juvenile but slowly gravitating towards adulthood. I felt a manga-inspired style best suited it. Hell, I may very well be wicked wrong, but this is what I feel is best at the time.
Dude, I love drawing. I do. I would jump into a tank filled with man-eating cicadas if I found that I would be unable to improve. I'm sure any artist would. Artists are always trying, testing, failing, crying, pulling out hair, just to get that... that thing! Yes, being Japanese-inspired means that artists like me are influenced by a certain culture, but heck, we're social creatures, and that's what's going to happen. From this may stem that "something greater" you speak of. Or not! Who knows?!
I honestly don't think the Japanese style doesn't drain youthful minds. It's something for them to try out and practice with whilst they build their skill.
F**k. I wrote too much.
