People with disabilities are not second-class citizens, any more than women and people of different ethnicities are. Change is happening, and it is for the better.
Today, I am sharing an essay by a deaf man that I identify very much with. I honestly cannot say any of this any better than he has, and I will not try; instead, I am re-posting his essay for you. I hope this explains many things to you that I cannot say.
Deafness is not as bad as people think it is. It's not a life-ending disability, especially not with modern technology. Here's my opinion of it, as someone who was born with deafness and has learned to live with it all her life.
