Well how would you describe today's society views the deaf community? Would you say it hasn't moved on at all? I might not be doing a massive amount to make sure things change in the future, but I'm on this website to learn as well...
Start reading. There are any number of threads that discuss the hearing population's views of the deaf. You might start with any thread related to audism.
Accept what the deaf tell you their experience is, and has been. Don't try to minimize it by saying, "Maybe you misunderstood." These are the experiences of real people, and the effects they have on them are real. It is easy to fail to grasp the human impact when you are sitting behind a computer screen.
