Mr. John Sherwin:

I will mention something about bias. It is often unconscious, and it is not always clear to someone that they are being biased. When you are in an environment with deaf and disabled people, they can spot bias more quickly than someone who is not disabled or deaf and they can bring it to your attention. Often, well-intentioned development of products and services includes bias. Even though the people developing them are following accessibility guidelines and doing their level best, that bias can be completely unconscious. People are not aware of it until it is pointed out later. When people see it, they question why they had not seen that before.
