Okay, no, I had to make a second post to elaborate on how stupid this 'Katara' one is.
First of all, in context of the Avatar universe what she's saying makes no damn sense. Yeah there are no 'white people' but there's still one fucking group trying to commit genocide and subjugation of the others. "Oh no, the Japanese are trying to burn our entire fucking continent to a crisp again! *But it's okay, because they're not fucking caucasian!"*

Secondly, 'hurr durr white people am bad' is the most uneducated moronic shit ever, and about as accurate as Hitler blaming all the ills of the world on the Jews. First of all, I'm assuming the moronic twat meant 'Europeans', and for future reference Europe. Isn't. White. Second she's one of those tumblr dipshits who likes to think that literally every other country in the world would be holding hands and singing fucking kumbaya around the campfire without Europe and America, and that the other continents and races are filled with innocent fucking victims who never hurt a fly throughout human history.

I thought the whole point of Avatar was that great good and great evil can come from anywhere, no matter who you are or where you grew up.
