So going through this thread, I feel, is a pretty accurate representation of race-relations in our society right now.
The systemic whitewashing is something that absolutely happens in American culture. Throughout so much of American's musical history, styles are almost directly lifted from African Americans and then adopted by a white singer. Back in the 50's this was absolutely rampant and absolutely no credit was given to the influence. Black culture has continually been borrowed by prominent white artist and made their own.
As Paul Mooney said, "Everybody wants to be a [black american] but nobody wants to be a [black american]."
OPs claim is part of a larger issue. The erasure comes due to Fortnite BEING this juggernaut pop-cultural staple. With the popularity of these dances, while it seems completely innocuous not knowing the origins of the dance, it just contributes to the larger issue of things that black culture has created not getting it's due credit.
It seems many people are sitting there like, "You serious, OP? What's the big deal? You're taking nothing and turning it into something." While it's not NOTHING, it certainly isn't a HUGE deal but it's these micro-instances of waiving something like that off that contributes to the overall problem.
I mean, the Fortnite argument is not worth staking your flag and fighting to the death for, but it's a good starting point.
Another thing that was used as a counterpoint was about how people are complaining about the Smash Bros. roster not being diverse. Just wanted to give a quick touch on that (even though these kind of things deserve a much larger discussion space). Now, while I'm not excusing Japanese culture for it, you have to understand as Americans (and this board is primarily an American board), is that just because America has a more advanced view when it comes to diversity, that doesn't mean you can use that stick to judge all over countries. I mean, on paper, yea, sure that'd be great, right? But in reality, due to historical and societal factors, that is just a naive approach to take.
In the case of Japan, an already xenophobic society, they don't have that much interaction with people of other races, ESPECIALLY skin color. In Asian countries themselves, just a darker skin tone is looked down upon. The Chinese, Korean, and Japanese population look at Western Asians like they're a lesser group partially due to them being a darker shade of skin.
Horrible, right? But the issue is because these countries lack the diversity that America provides, they don't get challenged by this very wrong way of thinking. Most of them don't interact with other races on a day-to-day basis to realize that we're all just humans.
To compound things, the only exposure they get is what culture gets exported.
Consider this, around the mid 2000's when I went to visit my home country, one of my cousin's asked me if it was true that if you looked at black people the wrong way... that they would pull out a gun and shoot you. I thought it was such an absurd question to ask but then I realized, HIS only exposure to African Americans had been the movies and rap music that America exported. 'Boys in the Hood,' 'Menace 2 Society'.... it made since he thought that way.
So when taking these factors into consideration, it isn't right, but it makes sense that a game developed by Nintendo of Japan will lack the racial awareness and sensitivity of showing a diverse cast.
I mean, just look how the Pokemon Jinx. CLEARLY created as a caricature of African-Americans. Nintendo of America had it swapped to a purple skin as a quick fix.
Remember that Resident Evil 5 controversy? Showing a white protagonist gunning down nothing but Africans? Their culture as a whole doesn't understand the deep history of slavery in America. While yes, you can read about it in textbooks, it's different being raised in an environment that still struggles with that past. To them, it was just "Hey, our setting is Africa so why wouldn't the zombies be mostly black?" Makes sense on paper but a game like that just doesn't work in America BECAUSE of the intense history behind those imagery. They ended up peppering in white zombies to offset the negativity.
In the same coin, though, I wouldn't expect an American audience to fully grasp the dynamics between the East-Asian countries. It use to anger me as a child when American schools just glossed over the Pacific portion of World War II in class. It's only mention was the atomic bombs and that was it. The actions of the Japanese during this time STILL affects relations between Korea and China not just politically but also artistically.
You'll notice a LOT of films where Koreans or Chinese are just beating the shit out of Japan. In the same way American culture revels in beating up Nazis, Koreans and Chinese culture revels in beating up the Japanese (Look at IP MAN and THE GOOD, THE BAD, AND THE WEIRD as examples).
However, I wouldn't expect American culture to fully grasp the history and weight of that situation. And it sounds ridiculous but the imagery of Japanese people killing OTHER Asians in 'Ghost of Tsushima' felt a little gross to me. In the same way if America released a movie about Germany post World War I where America is the antagonist would sit funny in people's mouths. Again, I don't expect someone to understand the weight of that dynamic.
These are extremely complex conversations and I would argue a bit too intense to properly be discussed within a forum like ResetEra. But, I think a forum like ResetEra can challenge the people who don't think this is a big deal and encourage them to dive deeper into this topic should they be so inclined.
