A 90-year old man, who was a war-hero in World War II, just came out publicly as transgender. He (now she) says she's always known since age 3 that she was this way. (There's something about that particular age: it was the same for me.)
What kept her from living virtually her whole life as a woman? Social oppression. The cruel refusal of others to accept her as who she actually is. Thirty years ago when she was 60, she cautiously ventured forth but was slapped back. A too-familiar story.
All we really want is the opportunity to live our lives authentically. We don't cause trouble, just seek the freedom to be ourselves. Why is that a problem for other people?
