Mirya has the whole reason.
No body neither yourself can change who you are but the problem is that in one sense we are the result of what the enviroment makes in us.
Example: women for centuries saw themselves as servant, objects, there was nothing in the world that could show them somethingf different up to the moment that some women had a "vision", were illuminated, if we can say in a different way that they were human with the same rights as men. We now know the results of that beginning. When that did happen? How did that happen?
Applying the same concept, we were in men up to the day that we can be what we are mean to be, but it must be a physical process, a mental process to reach the point that we are a woman, for the meantime they use the word, transgender, transsexual, it doesn't matter ut the day I realize who I really am, independently of the external peel or appearance, there's nobody that can change and the world won't have the tools to.convince me of the opposite.
