No good way at all. :( The problem with trying to quantify it is that everyone is going to view relative levels of 'crazy' differently based on their surroundings and upbringing. It doesn't help that the idea of a sliding scale (sexual, gender, mental health, or otherwise) seems to confuse almost everyone. I have faith that they'll figure it out one day, though. That will probably involve not leaning so heavily on the perceptions of others, which is hard.
