Why do you keep questioning what the deaf are telling you? You ask the question, you are given an answer, and you ask the question again. It would appear that you are attempting to manipulate the answer you want, rather than accepting the answer you are given.But do you not think that perhaps the amount of deaf people bullied have maybe gone down?
You say you are here to learn. Stop arguing and minimizing, and pay attention to what you are being told. People are trying to help you learn, and you are resisting the efforts.
