It's not about being okay about it or anything. It's hard to compare, but let's say Africa. No one is "okay" with the fact that people there have their rights, food, money and even health sipped out of them by people linked to rich countries' millionaires, but not everyone wants to make the effort of dedicating their life to helping those people.
In the case of transgendered people, the price to pay is not money or time like with Africa; it is to be partly stripped of the "normal" life one has struggled incredibly hard to get.
Sacrificing oneself for the others is good, but not everyone can do it, and on ->-bleeped-<-/transsexualism, I am not sure I can either. Some people are okay with being fully open regarding their "special" status. It's great. But not everyone is capable of maintaining a mental health and happiness in such a state.
Being open and honest is a plus, not an obligation. Similarly, choosing not to outright reveal secrets is a right, and whilst willingfully refusing to use a right to defend that in which one believes in and for the future generations is good, it is not an obligation.
To continue the comparison with Africa, being absolutely open about one's ->-bleeped-<- is not like chipping in a few dollars a week to feed the poor or signing a petition to force a factory there to be more ethical. It's like becoming a politician and working every day, without ever being able to retire, to change politics regarding Africa, or to enroll to be a missionnary over there.
It's no small thing. Transgendered people struggle with an enormous amount of problems already to just be allowed to live. It is not on THEM that a life-long burden must be placed. That's what activists, petition authors and politicians are for.
