Y’all realize that in the time period District 12 was based on (turn-of-the-20th-century America), Italian and Greek folks weren’t considered “white,” right? And the fact that those characters would be considered white now doesn’t mean that the social and racial implications of them identifying as a non-white ethnicity in their culture just go away.
If you’re going to use the argument that people with olive skin can be white, then you have to consider the fact that in the historical era District 12 was based on, people with olive skin weren’t “white.” In fact, anyone who wasn’t originally from specific parts of Germany or England was not considered “white.” So when you’re saying that Italian and Greek people can have olive skin, that’s true, and Italian and Greek immigrants were largely the ones working the coal mines in turn-of-the-century Appalachia, but Jennifer Lawrence and Liam Hemsworth are not Italian or Greek.
In fact, in both the time and place their hometown was based on and in the time the series is set in, they’d be considered white. Katniss identifies a shared culture and set of physical characteristics, both distinct from the privileged and decidedly white majority group, and her description of Seam people meets just about every one of the qualifying factors for an ethnic minority group (none of which, incidentally, are indicators of geographic genealogy). Whether or not her ancestry is European, in her culture, she is a woman of color. That’s why it bothers me that Jen Lawrence was cast as Katniss, although since her performance is wonderful and there’s not much I can do about it now, that does not make it not whitewashing.
Luckily, I’m skilled in enjoying things to their fullest despite finding problematic aspects to them!
