“The fact is, “anime/manga” are marketed as something distinct from western comics because it is convenient for the publishers of these products. To put it another way, they have brainwashed their audiences into being antagonistic to non-Japanese content because it is a great way to defend against competition in the marketplace. By subtly convincing readers that they are taking part in something completely different and superior to “western comics,” they essentially prevent the loss of sales to other companies.
It’s not just anime/manga publishers allowing this to occur, either; there is a similar attitude of disdain among western comic fans which is allowed to persist.
This is why you see different sections for “comics” and “manga” in stores, or an “anime” section and a “family” section for animation. You will almost invariably find the American animated series Avatar lumped in with the anime. It is not uncommon to find Scott Pilgrim in the manga section as well. There is a reason these things are located there and not in their “correct” sections. It isn’t because the people putting them up don’t know any better, either.
It may be convenient to breed this attitude in the short term, but in the long run it is damaging to the artists that produce these things and fosters stagnation in content. When the audiences stop going along with this sort of thinking, publishers will be forced to embrace a wider variety of styles and talents in order to keep producing things people are willing to read and watch.
The long and short of it: if you believe that anime/manga is a style, you are incorrectly being led to believe so and it is ultimately bad for comics from any country.”
