You are simply wrong about this, that is not the cultural attitude that generates this response in something like 95%+ of cases.
Capital-D Deaf culture does not as a rule view their lack of hearing as a horrible wrong that needs to be corrected for them to live a “normal” life. They believe that they are living a normal life, and screw you for suggesting otherwise, and many would tell you that they do not want to speak your inferior language anyways, because it is broadly technically inferior due to its inherent one-dimensionality: you describe things with a scalar pressure varying with time only, their language describes things with motions in three dimensions of space as well as in time.
This means that in the 95% case, the dominant attitude is not “I’m afraid,” it's “those folks are assholes half the time, why would I want to join them if I don't have to?”. It's a cultural objection rather than a physiological one.
