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?
Every single right leaning person I know LOVES several movies and shows that have main characters that aren’t white men.
The boondocks, blade series, basically anything Morgan Freeman or Samuel L Jackson have done, Lando, Morpheus and uncle Phil off the top of my head.
I am aware there are the super racist far right guys that probably can’t even watch Scooby Doo because the dog is brown, but the grand majority of “right wing” people aren’t white supremacists that lose their shit if a character isn’t white in their movies and shows. Even if that’s what some people here might tell you is the case.
