I'm gonna jump in here, if you don't mind? I can't speak to being deaf, per se, but I can speak to what you said about political correctness, which basically, gets on my last nerve!
Another term that has been batted around in recent years, is "physically challenged..." Basically, it means the same to me as "hearing impaired" does to most of you. It seems to white wash what we face, and "make it pretty" for other people.
Well, I believe in calling something what is it... I was born disabled, and I have absolutely no problem saying it. I'm sorry if that offends some people, but tough. It's who I am, and I'll be damned if someone is gonna to change that about me!
