> Everything you just said also applies to someone who's deaf, blind, or physically impaired.

A blind person is not a good bus driver. A physically impaired person is not a good mover or yoga teacher. A deaf person is not a good session musician. A person who cannot function sitting in a meeting with 3 people for an hour is not a good employee where that is required. What makes the last one special compared to others? They can be a great yoga teacher/bus driver/session musician/mover, I just don't see controversy
