What Do You Assume to Be True about LGBTs?

During the course of this semester, I intend to research about this population. I want to learn about what really brought about LGBT and how the general public view them. I am eager to know if my own personal opinion about this population is right or wrong. My assumption about LGBT is as follows:

1. They are usually people with same sexual orientation
2. One partner play the role of the husband while the other the role of the wife
3. The male husband sometimes dresses like a female.
4. I assume the population choose their sexual orientation by fantasizing the other partner
5. Majority of the population are introduced into LGBT either by their parent or close associates
6. There is no medical diagnosis related to LGBT. Therefore, this population chose who they are.
7. I assume this population is trying to exercise their right to association. This is a country where people think it is their right to be what they want to be. Isn't it?
8. Some of this population is been traumatized or raped by the opposite sex; hence, they have no feelings for the opposite sex.
9. Some of this population hides their identity for fear of being rejected.
10. Legality of this population by some States increases their recruitment rates.

Most of the information I learn about this population is direct observation of some member of this population and some of this information is just what I heard from other people saying about LGBT. In fact, I have a friend whose daughter is a member of this population.

Some of the challenge I may face during the course of this research are time, cost and ability of some selected member of this population to respond truthfully to some of my research questionnaire.
