You mentioned in an earlier post that Anime's influence came from earlier Disney films. Very true, but what is not mentioned was that Japanese animators didn't have the budget nor the method to rotoscope their actors(Yes Disney rotoscopes). With these limitations, animators saw fit to rely on alternating between beautifully rendered still shots and 2-3 frame animations.
The major difference between Japanese/European and Western comics was the Western's interpretation of a comic book aka "the funnies". That one label has held us back from branching into different types. Cartoons are kids shows, nothing else. Mean while Europe and Japan are making comics and cartoons for all ages. Astrix, Tin Tin, Smurfs from Europe. Dororo, Battleship Yamato, Speed Racer from Japan. Even when theses cartoons were released in the US it was re-dubbed to protect kids from topics of death and pain. Yes it's true in the 70's we tried to curve the minds with movies like Ralph Bakski's "Wizards" and "Lord of the Rings" or Clive Smith's "Rock and Rule". Even Disney tried with "the Black Caldron" and learned that in the West, kids couldn't handle death. In the end Disney was king and the king created for the children.
So when Otomo's "Akira" came and showed us what Japanese Anime REALLY was, we where hungry for more. To confess, I lived in Toronto, Canada when I was a child. My exposure to comics were Tin Tin and Heavy Metal (when I could trick them into selling it to me). I knew from an early age that comics weren't just for kids. This is what Anime did for many comic artists, I think even you. It showed western artists that we are not limited by topics of comedy and super heroes. It reopened the creative gates and showed others why we watch, draw and praise foreign comics. It freed us of comic book heroes dressed in costumes and talking animals used to amuse the young.
These stereotypes you are uncomfortable with are NOT reflective of an art style nor a slap in the face to artists. It's a reflection of what is stereotypical exceptable within that country and its history. It is a visual marker to readers so they know what they are walking into. Look at "the Boondocks" or "the Last Air Bender". Both are Anime in style, telling the viewer "hay this is going to get crazy."
They are not labels of stereotypes but labels of inspiration.
Like I could draw pure manga inspiration ..but if I wanted to sale a manga chances are I'd have to go to japan and as closed as Japanese society is along with the low pay and difficulty of making a hit manga , success is unlikely =/ but possible , yo boy Felipe smith did it . Or you can try Korea and relabel it Manhwa and learn Korean . Chances are not going to sale a manga style comic here in the USA through traditional means . (There Marvel and DC , then there independent then there the " Expensive High brow" Graphic novels aimed a very small niche of people ). Markets and publishers are very entrenched and culturally centric (if there a market... if there no market , your kinda screwed really ) So if folks are generalizing by country in relationships to a market there usually correct , But individual ? probably not . . Lucky there the internet where you can find any audience and self fund with kick starter and be your own pioneer ,
Artist aren't limited to the country style . There markets are though ,usually retail market in particular are very much bounded to the local audience (and the more expensive the product take to create ) . Though on the web and the internet yeah not so much or a place like deviant-art . Think that the main problem to be honest you can draw any style but your limited to the particular market available in your country and usually the easy way out is to find a publisher . If there is no market then you just do outsource work for another country and making sustainable income on the internet is difficult despite having a an audience anywhere in the world. With thing like kick-starter finally changing .
