The issue is a lot more nuanced than “Asian people hate Blacks” but it undeniably exists. People seem eager to talk about the complexity of race relations when it’s in their own country but feel the need to impose and then debunk cartoonish notions of race in other lands. Even in the depths of pre-integration South, Americans were still proud of Jesse Owens winning the Munich Olympics and all but the most racist Americans today still enjoy sports teams that are predominantly Black.
The restrictions on race placed on Black Americans today are rarely at the level of straight boycotts, domestically or abroad. Rather, it’s a conservatism about the white male default and antipathy towards breaking that mold. For example, it’s exceedingly hard to name a movie in which a Black man is romantically involved with a White woman, unless that’s the plot of the movie. Denzel Washington has apparently never appeared in a movie across from a white female partner and Will Smith, only once or twice. On the contrary, White men are paired with Black women all the time in a much more racially neutral way.
The issues to do with Asia aren’t all that dissimilar to the conservative elements in our own country. Remember the “controversy” when it was revealed that in Spectre, James Bond would sleep with an “older woman”? These tensions have always roiled movie production since the very earliest days of film and the growth in the Asian markets is simply shifting the balance in numbers towards a different direction.
For the most part, it doesn’t have an effect on the average person reading this forum. The type of movies being made for the “other audience” barely crosses our radars. It’s stuff like Paul Blart, Mall Cop and Transformers which purposely attracts a more conservative audience.
But just be aware that for every “controversy” like the Spectre one, we only hear the voices of the domestic debate but movie executives are watching numbers coming in from around the world and the silent audience that is talking about these movies in another language, in other forums are far more in alignment with the conservative voices in our culture. That makes movie directors lean towards safer choices and blander material to cater more towards global tastes and that has an impact on everyone who is not part of the mainstream.
It doesn’t affect Black male leads in a serious way because Black male leads are already part of the mainstream but it affects Blacks who want more and different roles in film and are pushing for more varied representation and less reliance on stereotypes and tropes. That’s the real impact that Asia is having on the American movie scene.
edit: The good news is that there’s no intrinsic reason for Asia to be more culturally conservative and it’s more of a factor of the relative recency of media as a force in their culture. As the countries get richer, better educated and more worldly, there’s going to be the emergence of a large market demanding the same complex, nuanced, challenging films that we demand in the West and that’s going to buoy a new renaissance of great populist film making.
