I'm not here to study anyone. I'm deaf, too. I just enjoy thinking and I'm hoping to relate to other deaf people in ways that are meaningful to me.
I'm also very interested in improving life for deaf people. Whether or not you know this, most of us are either very sheltered or have an unreasonable amount of crap to deal with by an accident of birth that in no way effects our intellectual capacity except for how society denies us access to that capacity.
You know, I was thinking more about the question of whether I'm here to "study" people. The answer is still no, but now that it was brought up, life is a bit boring for me without studying it. I prefer to examine myself, others and society and use my brain to come up with ways in which things could be made better. Step one in "making it better" is always figuring out what's wrong with it as it is.
