Anyone mention xenophobia yet?
I see it on GAF and in the video game industry in general with the way the media champions Western titles, Western studios, and the only Western console maker.
People use slurs like Weeaboo to put down anyone with an interest in Japanese culture or Japan's media exports (some people definitely get weird and "culturally appropriative" about it, but that's besides the point) and there are some pretty ignorant attitudes openly expressed in generalizations about Japan in general. That's even before you get to any aspects of Japanese culture or media that people find offensive, or that makes them uncomfortable, people feel it's acceptable to generalize Japan in such a way that everyone are some weirdo otakus or something. "lol Japan" and such and such.
People are threatened that a culture that is so different and "exotic" could be appealing to the youth to the point that imported media can be more popular than domestic media. Think about that, the U.S. is usually the one who supplies the rest of the world with our films, shows, and entertainment industry and here is Japan who not only fills a niche that Americans don't even really produce content in the same vein as, it also has all the appeal of this non-western Japanese culture at the heart of it that makes it just different to other entertainment. I can't think of another area which that is true; there is the occasional show or film that crosses over for an American audience that is made elsewhere but it's the exception.
So even when stuff like Anime and manga is HUGE in the U.S., it will be regarded by it's "otherness", as a "niche", even though a significant portion of the people buying it are white (not unlike hip hop). Meanwhile, white people will also be mocked for consuming that media (not unlike hip hop) while being called derogatory names and the mainstream will appropriate and leech of that culture while not ever giving it the recognition it deserves (not unlike hip hop).
