Gender confusion

It is estimated that 0.3% of all American adults are transgender, but there is no agreement or definition on what that is or how you get there because it is based on a feeling about ones identity, not on biology or fact. "A transgender identity is not dependent upon medical procedures. While some transgender individuals may choose to alter their bodies through surgery or hormonal therapy, many transgender people choose not to do so." (Pew Survey, 2013)  I know anorexics who sincerely believe they are obese, dog owners who sincerely believe their pet is a member of their family, amputees who can still feel their missing limb, healthy people who believe they are sick and helpless, and rich people who live in fear of poverty. The feelings are real, but do we change laws, regulations and common sense to accommodate their feelings?
