Could it be said that this is a pattern or that someone who comes to this conclusion is exaggerating?
For example, in many animes the characters are Asian and right-wingers don’t seem to mind. Maybe because most of the characters appear to be white, or because many Japanese animes have an actual cast of white characters. They don’t seem to mind if in a fictional world all the characters are white or Asian, but on the other hand they would mind if in the fictional world all the characters were black or had dark skin. Is this really a fact or an exaggeration?
It’s real, but you don’t get to see anything from billions of viewers who don’t mind or even enjoy a little variety. Only the five hillbilly snowflakes who feel offended by a skin tone bother to voice their stupid opinion.
