Broadly speaking we tend to see society become a little more open towards different groups over time, and with that comes slowly but surely increasing media representation of them. A cynical way to look at this is that it’s simply because their existence has become profitable, and that’s certainly a very valid way to look at it given the slew of middlebrow oscar bait exploiting historical prejudice and hamfisted tokenism. A more positive way to see it is that media representation gives us a platform to humanise different groups, to become aware of their existence and their validity as individuals. I believe both perspectives can be true at once, and in that sense there needs to be conscious thought about how representation is implemented.
