I see them as great events for people to meet and gain more understanding, especially important to those that are new, or lack access to good information. Though, not only did I not goto the one locally, I probably never will without a specific purpose.
Don't get me wrong, I want to help people and even once I transition I intend to stick around and give people advice and whatnot, but I think I would prefer to look at my ->-bleeped-<- as an open secret, rather than something to show off.
I am not saying that I want a normal life per se (even if such a thing were to exist) but, I do at least not want to have to carry my past around everywhere I go. When I was a child I was homeless for a time and that has made me be active in trying to confront that problem too, but I am not about to go around and say "Hi I am Hikari, formerly homeless as a child".
I am me, I don't want to be defined by any one thing, and sadly people love to define you by one thing.
