One of my greatest fears as a child was that I would be just like all the other people around me. I do not believe homosexuality is a disease. I believe God made homosexuals for a reason. Straight men seem to be good at building buildings. Gay men, like Michelangelo and de Vinci, were good at designing and decorating buildings.
Homosexuals seem to have gifts to offer the world.
Changing that would be changing God's will. I view sexual orientation in the same light as other differences such as hair color, skin color or height. It is my expectation that many preferences are wired in to us. As an example intended not to trivialize the situation but instead draw on a lowest-common denominator, I prefer chocolate rather than vanilla. Vanilla is what the vast majority of people prefer.
