vulnerable population

I think I should learn more about LGBT populations over the course of this semester. This is the population that has  lots of social and political negligence. They are struggling against of the society for their existence. Many people are fighting for equality between LGBT population and other. I assume that these people are not treated equally even today. I learn about LGBT population from other people talking about them. The most difficult challenges that I will have after doing this research population is there might lot of argument form the readers view point about my study.
