Ditzy:
My question is :
Why do you think you "owe" them an explanation?
Its really none of their business isn't it?
You wouldn't go around calling attention if one of them put on weight would you?
Seems these days people feel the need to "come out" about almost anything.
Are they searching for acceptance or something else?
I never understood that mind set I just did what I felt I needed to do for my reasons not someone else.
What I do is my business not friends or family.
If its a spouse then I can see it being a thing that needs to be talked about between the two.
I saw a lot of that when I worked part time at an LGBT center but never got a firm answer from any of the people.
Your question isnt really a good one, because the answer is a simple no, and that is simply irrelevant to what seems to be the issue (people wanting to be honest to others about who they are, etc etc) so we cant get much out of it.
Human beings have evolved to have certain qualities regarding social behaviors. For example empathy. It is easy to understand the positive social effect that this has on a community level. Similarly, honesty works in a similar way. It has a certain social result and simply, societies with members that were more honest survived more easily than those with less honest members. And honesty works a bit like this: When you think people have a false idea of something, implying that you have an other idea that contradicts what others say and you sense that yours is better, then you want to let everyone know about your idea about that thing and how it is better! In the examples you mention, the subject, the thing people have false ideas about is the people's identities that want to come out of the closet.
This is natural and okay.
What is moraly horrifying is that our society will not allow them to be honest. It will shame them, it will make them fear to do it!
This is hubris.
