I appreciate the comments. I do not have any doubt that the average homophobic person would say they could never move on the spectrum towards desiring the same sex. In my mind this would only display the person's lack of introspection. If we are making anecdotal evidence important then I might note that most research students that I have spoken to about this agree that they could concieve of themselves over time being able to move on the spectrum to desire the same sex. I think this is an important point for Christians who believe that homosexuality to be immoral. If they cannot admit that it is possible for them to move on the sexual spectrum then they cannot ask others on the homosexual side to move to the heterosexual side. To do so would be very hypocritical.

Now, whether one believes that those on the homosexual side of the spectrum should move to the heterosexual side depends on whether or not they believe God has set standards for sexual ethics that are more comprehensive than a loving committed relationship with another person (Of course the Bible itself presents homosexuality as immoral, but then again theological reasoning does not stop with the Bible). I think that another point to be considered in this conversation is that if a loving and committed relationship is the standard then what about other sexual activities in which this is possible outside of homosexuality. I would be interested to hear what Lynn thinks about incestuous relationships with one's sibling or parent. If the overarching principle is a loving committed relationship then I can see no reason why an incestuous relationship could not be considered moral, if of course both consenting members of the relationship are fixed not to have natural children.
