Sure. Call me whatever.
England is the worst example you could make, as far as I know it started going multicultural in the 16th century with Henry the VII and the Orient Spice trades.
But I'm not talking about these very specific settings in which you are unlikely to see anything but white people or poc. I'm talking about these everyday movies. Like love movies. Comedies. Action hero movies. Set in our times. There's no real reason for everyone in a contemporary movie set in the US to be white. For example
this picture. What harm would it have done to have a black actor sprinkled in with these reporters? As much as I know about the black to white ratio in the US, at least one of these people should be black for it to be an accurate representation. This is what I mean by "there's no reason for every character in a movie to be white". Sometimes you don't even get background characters to be diverse, making the main love interest black should change 0 about their character and everything about their ethnicity's representation in media. If it changes their character, they've got the wrong actor.
Of course it shouldn't be "Oh look we have black actors instead of white ones, look how inclusive we are buy more tickets watch this movie". But sometimes, you've gotta ask yourself how much of their character depends on their skin colour. If none, I don't think it needs to matter.
However, as long as people care about the skin colour of a character that doesn't have a specific reason for it to be any tone in particular, they'll make it out to be the selling point even if it means nothing in the grand scheme of things, I guess
Honestly though, some whitewashing is just atrocious. Tiger Lily in that Peter Pan movie? For goodness sake, her whole character consists of "is native american". Casting a white character here is just... dumb.
Uh anyway end of rant. Sorry about that.
