It's not right for anyone to tell other people how to live. Blindness and deafness aside. Audism is just a deafness-specific case of people who feel the need to control others Syndrome. Often with a side effect of not being able to get past their own negative ideas about deafness.
If one want to be stay blind, I support them 100%. I don't mind helping them if they ever need it. You can be the most perfect person in the world and still need support from someone somewhere. No one is that indepedent from the society.
