A few months ago I listened to an episode of a podcast called Invisibilia and the topic was expectations. They recounted how expectations can have both positive and negative results, and talked to a blind man named Daniel Kish who has a remarkable sense of his environment.
What struck me most about the discussion was not the discourse surrounding sight or the lack thereof, but on the arguments in favor of or against the use of 'clicking' for blind people to navigate their world (referred to as echolocation). Many blind people are discouraged from clicking, it seems, as they are told that it is not socially appropriate. By whose standards is it not appropriate? By sighted people.
I find it appalling that individuals out there "helping" people are limiting functional behaviors which can foster independence because people with sight may not understand it or somehow find it uncomfortable. In this case, it's not blind people who need to adjust, but everybody else.
