I have discussed before the increased trend towards color-blind casting of films and TV shows, which I see more in British productions than in American ones, along with the related issue of cultural appropriation.
In general, I favor color-blind casting and have got used to it. To see people of color playing roles where they would not normally be seen in such positions, such as the aristocracy in costume dramas of a bygone period, seems increasingly unexceptional to me.
But I started to wonder if by having such portrayals, we might be inadvertently downplaying the racist repression that existed in those times. For example, in the TV series Bridgerton, people of color play lords and ladies in England a couple of centuries ago which is not even remotely close to reality. Would some viewers leave with the impression that this was the reality of those days?
It would seem that one would have to be massively ignorant of history to fall into such a way of thinking but given that there are reportedly people who think that humans lived alongside dinosaurs because they are portrayed that way in the cartoon show The Flintstones, one cannot totally discount the possibility.
