I think we just have to live our best possible lives and as individuals, we are the solitary arbiters of what that means. Anyone who says that we must be one thing or another is missing the point of all this. Transitioning is the act of moving towards a way of living in the way that makes the best of things, that makes this life worth living. While there are political ramifications, it is a deeply personal act and we all have to have room to process it for ourselves.
