They found two regions with multiple genetic variants most strongly associated with sexuality.
Translation: more gay men had a certain genetic variation than straight men, and the variance was not likely random. It means that some bit of homosexuality can be explained by genetics, but not all. Based on what is now known, homosexuality is thought to be around 20 percent genetic, 80 percent learned predisposition. As time goes on, the 20 percent keeps going up, and the 80 percent keeps going down. I seriously doubt science will ever declare gayness to be 100 percent genetic, although it likely is in some people. For most, homosexuality is "learned." It comes about as a result of cultural and subcultural influences, group dynamics, personality, motivation, attitudes and a whole host of other things that influence all of our behaviors.
Most things like homosexuality start out as a fixation. The fixation becomes a compulsion, and then the compulsion becomes an addiction. Alcoholism, drug addiction, gambling addiction, and shopping addictions all come from this pattern. So does transgenderism, which is undoubtedly a learned predisposition. Homosexuality is a bit more of a grey area, although I would compare it to alcoholism in the sense that the combination of learning and genetics can increase someone's likelihood of taking up either behavior.
Fixations can come from any number of sources, including mass media. The more mass media glorifies a particular thing (transgeenders and gays, for example) the more people will become fixated with that thing, and the rest is a numbers game; as we have seen in recent years.
