Jillio,
You know, I think you are a very intelligent lady and want to understand everything. But, being deaf/hoh is for someone else, not you, to understand.
You see, each of us who are deaf/hoh were created by God for His reason. We don't know the why's or the how's of it, we just are. Most of us accept it. Most of us want to make the most of it and be productive members of society and pursue the American Dream (for those in the USA).
But . . . you are a hearing person. You may think you have the tiger by the tail, but you don't know all of the story. You see and read our stories as a third party, never the first party. Someday, when we have more deaf/hoh people in places of authority in government and education and the like, you will learn that we will not take things sitting on our hands.
