I'm going to bet that you have more interactions with a sad cup of microwave macaroni than real people. Real people tend to not get hung up on one issue ad nauseum, as you seem to do.
Now I realize you were the original poster on this thread, but surely even YOU have realized by now that over time, in every thread I have seen in this forum where the discussion turns to diversity in entertainment, your input becomes the flaming bag of poop on the porch of discussion. (analogy.. I am not literally calling you a flaming bag of poop. I don't know if you are a flaming bag of poop, or flaming gay or flaming straight or just a small sad barely glowing ember of cognizance or even, remarkably, something altogether different) . Rather than recycle all the comments people have made before that you don't like to listen to, I actually have a solution for you:
Learn Russian. I am quite serious. The Russian film industry, while not as vibrant as it was in the good ole days when MosFilm was the biggest studio on earth, it still exists, still makes a lot of content, including sci fi and it is remarkably un-diverse. You can be happy, you can rejoice in the community of your fellow aficionados and apparatchiks of an industry that seems to have skipped time. And the bag will burn forever and no one will stomp on it.
