There are many reasons to keep it privacy as much we can, as you may seen it so far about not revealing my name or even in pictures. It's because of job situation, especially for my wife. She get to meet many deaf people every day and if I bring up something that is very controversial related to deafness and if that client is a member on AD get outrage, that client will scream at my wife about what happening on AD during 1 hour therapy session instead of getting self healing. You know? Sometime many deaf people get misunderstood so many times. So, my wife have pictures of me in her office and don't want clients to get recognized.
Secondly, due to my job if I get any flame war and get lot of attention toward me, just like what happen to Berry Sewell (I'm sure many know him) and he get lot of attention and get all bad mouthing him or threating him or whatever... I can get suspended from Top Secret Security Clearance and I'm not able to do my part of my job and even I can lose my job. You know many of the security agents do not understand about Deaf Culture, it's nothing like what happen to my former CEO of old job that he lost security clearance due to report by his ex-wife that he abused children. He didn't abuse children, I know him very well. It just part of his ex-wife's revenge.
So, there's a valid reason for keeping privacy as much as possible.
