You might want to check what year that dictionary is. Homosexuality hasn't been classified as a "disorder" since, I think the 70s (not sure when exactly it changed).
Well, sort of. It's no longer classified as a form of insanity.
We know what "causes" homosexuality biologically speaking, the same thing that causes any kind of sexual behavior. In fact most people on all sides of this discussion know this but many choose to forget it when deciding to make arguements.
All sexual behavior is governed by chemicals and pheremones that people emit and receive, this is why it's possible to castrate someone by removing the relevent organs and removing their sex drive. Neutering or spaying an animal, or removing the testicles of a male human... you do that and the behavior goes away as the person is no longer giving, receiving, or reacting to the impulses.
Granted we do not fully understand all of these interactions with the brain, but really most people know how it works for everyone. Humans really aren't all that complicated despite how we like to see ourselves, on a fundemental level we're much like any other animal, which is one of the reasons why we can be so easily predicted through things like psychology and sociology (and people make fortunes by exploiting this through things like advertising). Granted our form of self awareness does give us some resentment of our condition.
At any rate what a homosexual or bi-sexual is, is someone who is reacting to the emissions of their own gender as opposed to the opposite gender, or in the case of bi-sexuals are reacting to both. Like any form of biological reaction it seems normal and natural to the person involved because it is very much how they happen to be wired. Despite what we might want to think we tend to build a lot of ourselves up around our instincts rather than surpressing them rationally, and that is a big part of why things like psychology and sociology work.
Homosexuality is thus not a condition unto itself, but more of a symptom of other problems. Something that can be caused by a lot of problems, just like say a sneeze, an ache in your arm, or other symptoms. A sneeze could be anything from the flu to an allergic reaction for example. Albiet we're dealing with something less transient here. Thus some homosexuals might be born receiving pheremones that way, others might have their bodies adapt due to psychological stimula since part of the reception is mental (and the body can react to outside trauma in some pretty extreme ways), and for others it might come from a plethora
of medical conditions and malfunctions. We do not have a full understanding of this system and all of the things that influance it yet even if we know the basics.
None of this is pseudo-science, junk science, or anything else. After all anyone who has ever had a pet fixed knows this. Incidently the same medical conditions that afflict humans also afflict animals in many cases, so it's not surprising that as many people have pointed out there have been cases of animals responding sexually to others of their same gender.
Of course this gets clouded by politics. The gay rights movement generally tries to define homosexuality as something magical and beyond understanding out of fear that it will be "treated" largely because to the people involved it seems perfectly normal and natural.
There is a lot of political baggage behind it, but basically it's a medical condition. One that is biological more than psychological, but which can be influanced psychologically. But then again it can also be argued that with enough effort anything can be influanced psychologically, with enough time and effort spend brainwashing someone you could pretty
much turn them into anything you wanted mentally and even see physical changes in support
of it depending on what you did.
