In Megaman Discussions, you suggested that Chaos might have a point, Desert. He doesn't. Regardless of what may or may not cause homosexuality, hatred for it is never justified -- and a phobia of it is certainly irrational.
First of all, 'gene' is a generic term that describes a wide variety of DNA segments that beget all manner of observable -- and sometimes concealed -- phenotypes. A gene is not a single molecule that by itself dictates an individual's appearance and behaviour. It can be a unit, or a number of units combined, which tend to produce certain effects. A gene that tends to generate long legs in combination with a particular set of polypeptides might produce short, plump legs with another set. Genetics is not as straightforward as what most people imagine...
You ask: Homosexuality: Genetic or a personal preference? But you could have also asked: Heterosexuality: Genetic or personal preference?
Gay, straight, bi, asexual or what have you; people do NOT pick how they feel. It is a phenomenon that isn't easily explainable which involves their genome combined with development (and sometimes psychological influence pending life experiences). However, I will say this: Certain distinctions have been made regarding gay men -- their amydalae tend to be larger than those of heterosexual men (which could explain why the former tend to be more emotional than the latter).
Also, gay men tend to have older heterosexual brothers -- which tallies with the embryological cause I mentioned earlier. The more boys a woman gives birth to, the less testosterone is available for the latest male foetuses. Here is an interesting video which also highlights how DNA methylisation and epigenetics can play a role in determining an individual's sexual orientation:

Sexual orientation -- stupid, self-deluded, trendy teenagers aside who want to act 'cool' by being what they think is unusual or different -- is
never a choice.
