What he meant in his statement was that he did not choose to be gay. Read what is meant, not just said in words. Lifestyles are chosen. Life is not. You are born with life dimensions that manifest in different stages of life. The gay, straight or bi gender is one dimension of life out of many dimensions. Like it or not, it will manifest itself some time during your life. I do believe that it may be tied to the personality of the individual like favorite color and favorite food preferences, to put it simply. You don't choose to like certain foods. Either you like them or you don't. You don't choose to like a certain color. Either you favor it or you don't. It's very very personal and pre-wired in the individual.
