(and mostly for the better)

When I were a lad, telling the world that you'd rather be a woman was a good way to get you committed or at least get a visit to the Loony Bin. Ok, so it is a bit of an exageration but it was new and most so called psychologists at the time didn't have a round hole for them to try to force your square peg into.
There is some downsides to telling the world that your gender identity is not the same as your physical one. Some of the comments to posts from the likes of Jazz are almost obscene. But things are getting better. Over time the mortal sin of being in the wrong body won't condem you to a life of damnation at least in most parts of the world.
