Belief and Desire not Choosen

Beliefs are not something one chooses. I do not choose to believe there is a computer screen in front of me, nor do I choose to believe I am now typing. I just so believe. The same goes with desires. I do not choose to desire a glass of water. I just desire one. Why anyone would think it any different when in comes to sexual desire is beyond me. The whole debate about whether homosexuality is a byproduct of biology, while interesting, is complete red herring. Whatever the casual history of a desire it is not chosen.
