I think the whole point of the thread has been missed. Deaf people have a right to do their errands and go out in public without every single encounter being turned into an opportunity to educate the hearing world about deafness. Hearing people do the same thing all the danged time. Just nod politely and go on about their way. They have situations where they are busy and don't want to make small talk with a stranger. The difference is, the hearing person is allowed to feel that way because they are not being made personally responsible for educating a whole ignorant society. Why should the deaf be given that responsiblity. The point is, the deaf and the hearing both have the right not to be bothered with small talk with a stranger.
You nailed it! Thank you, jillio.
Minorities in general get put in this position where they have two options:
1) Play the educator role. Educate people in everything you do. Say upfront that your opinions are your own, your likes and dislikes are your own. Other deaf/HH people have their own opinions and likes and dislikes.
2) Be yourself and let people assume that everything about you is true of all deaf people as a whole. If you don't like to use speech, deaf people don't like to use speech. If you're oral, then all deaf people can and should be oral. If you know sign language, then all deaf people sign. If you had a bad day and get annoyed with the clerk at the grocery store, then all deaf people are pissy people. If you're a kind-natured person, then all deaf people are saintly and wonderful people.
Every interaction that a minority enters into with strangers gives them one of these two options. The first one is better for the group as a whole, but also extremely draining. No one wants to live "on stage" 24/7. The second is being true to yourself but also letting people make assumptions that may not always be true about you, and aren't true about the group as a whole.
This incident is a prime example. Kindly explain to the person that you are deaf and can't understand them? Or nod and smile and go on about your day? If you have good speech, do you risk using your voice and having the people around you assume you can hear? Or do you turn off your voice, and along with it the easier option for communicating in that direction? If you have a "deaf voice," do you risk using your voice and having people think you're stupid? Do you sign to them even though they probably won't have any idea what you signed? If you don't know sign language, do you gesture to give the idea you are signing? All of those involve navigating between 1 and 2. It's a constant decision the Deaf/HH, along with any other minority, has to make. 1 or 2? 1 or 2? Quick! 1 or 2?
