Because of the environment? Homosexuality isn't a disease. I believe people are born gay, however it seems to be that in SOME cases (like sexual abuse cases) isn't like that.
Comments: We neither born gay nor hetero, our behaviour are the result of the society we live in. In some societies, people have freedom to behave and to think, thus some of them will experiment whole sort of things which will build his personality and be either hetero, gay, alien or even serial killer.
In others societies, where there are less freedom, all people behave and think roughly the same way because of the teaching they received hence they become less tolerant.
Personally, if I had a child I would prefer that he will be hetero thus it wouldn't be difficult for him to flourish in the society and everything would be easier.
This is a ticklish subject. Biologically it doesn't make sense. Psychologically it is probably relevant. Socially its only now getting acceptance. For me I don't know. Most say that they always had this feeling and preference so I guess its something from birth.
I firmly believe that sexuality comes from birth, either genetically or hormonal induced in the stage of fetus, but I do not have any source to support this hypothesis and sadly, most people think it is a choice. Homosexuality sways been with humanity since the dawn of our civilization, just now, since, I would dare to say, the beginning of 20th century, our society is becoming increasingly conservative, maybe even since the victorian age.
Why would anyone in good mental health, suddenly turn homosexual? A group of people that is extremely discriminated, why would I choose to be in a group like that?
Even so, even if it is a "Choice", what is the problem? If someone wanna to have a [..], thatÂ´s entirely up to them and society have NOTHING to do with it, we need to be free to do as we like with our own bodies, as long it does not harm to another person.
ThatÂ´s my opinion.
I think it can be both depending on the person. Some people are born that way and others just choose to live this way for one reason or another. Whichever it is I think people should be able to choose how they want to be whether it is gay or hetro.
