Just Looking ...

When Professor Kalmar was describing his idea of the faceless horde, I thought of a possible similarity in cultures today. First I think I should clarify that my thought is not at all meant to offend anyone, and it is merely a strange analogy to the class content.
I was thinking about how people from a particular ethnicity think that the people of other ethnic groups look the same. For example, I have heard that some Asian people who have immigrated to Canada find that all white people look the same (or quite similar), and this is true in the opposite sense, for white people who have not lived in a culturally diverse area (they find it difficult to distinguish between Asian peoples, or perhaps Native American, Indian, and other ethnicities as well - whomever they are not familiar with). This can actually be quite an issue in eye witness testimony, as someone who is not familiar with another ethnic group could accuse the wrong individual of committing a crime, just because they look too similar (in the eye witness’s mind) to the actual criminal.
Anyway, my point is that, perhaps, the filmmakers of sci-fi movies (I, Robot, Lord of the Rings, Star Wars, etc) that include these “faceless hordes” of enemies (robots, clones, monsters, etc) could have based this concept on the supposed innate capacity in each race to over-generalise the appearance of other ethnicities. Perhaps this way of thinking worked a long, long time ago, before exploration and immigration, when different countries were ethnically homogenous and had to defend their land from other races. They viewed the “enemy” as one large mass of indistinguishable foreign features, just as the humans in the movies view the robots, clones, monsters, etc.
Obviously, this behaviour is not applicable to the world we live in today, as we all know to co-exist and treat each other as equals!
