A transgendered person is more than just someone who dresses up in the opposite sex's clothing. If you woke up one day with female genitalia but nothing else about you had changed, you'd still feel like a man, think like a man, and behave like a man. If you had to go to the bathroom, you'd enter the men's bathroom. Someone who is transgendered is, for instance, living with a penis and yet thinks, feels, and behaves like a woman. The genitalia is in fact the least important aspect of the issue. It's just meat and nerves and doesn't indicate anything other than if you stick it or get stuck during sex. The mental and emotional aspects is what truly define your sexuality.
