Nothing is wrong with you, I think it is something that humans do to protect themselves, I think everyone is capable of it, we do it to survive.
I was watching an old Stephen Fry talk this morning, he was talking about ordinary people who went to work as guards in concentration camps.
He was talking about the role of language in dehumanising people, but I think there is something deep n us that protects us mentally. It's a sport of, I can't cope with this, so it becomes normalised.
There was an ad that really struck home for me a few years ago - I can't find a link to the ad - link to an awards ceremony mentioning it below.
The ad is basically a small boy going into a public toilet, sticking his hands into the toilet, pulling up a mouthful of water and drinking.
Then there is the voice over, "Five million children die in the Third World from drinking water polluted with feces. . . . If you don't mind little black children drinking out of a toilet, you won't mind little white children drinking out of a toilet either. Or is there a difference?"
There is no logical reason for this ad to have had such an impact 20+ years ago that I still remember it, not logical in the sense that this is a well fed child being paid to act. On the other hand we do not see adequately clothed and fed white children drinking dirty water every day. Somehow the number of these ads make them normal.
