This has occured in all cultural exchanges where one group
tries to become dominant over the other. People in general
fear change. It makes them uncomfortable. As a result they
try to force others to conform to what they are used to
and what makes them comfortable. IE oralisem. The hearing
culture does not want to experiance discomfort at not
hearing ideas expressed. So they pretend to try and "help"
the deaf by forcing what is comfortable for them onto the deaf.
Note that the dominant group deludes itself into thinking that
they are coming to the "rescue" of the non dominant group.
The same has happend in other cross cultural interactions.
Time and birth of subsequent generations helps ease the
tensions but change is slow. Each generation should
feel a little less tension about the other after the emotions
have reached a peak. I don't know where that point is on
the graph right now. But I am hoping that as more Deaf are
educated and they in turn are able to train other Deaf on
the value of their own culture and their pride in it, that
tensions between the cultures will cease to exist.
