Attractions (such as sexual orientation), on the other hand, can be exclusively involuntary. I understand what you are saying and you make a good distinction; however, attractions, like tastes, can be developed through exposure and experience. Serial murderers were not born that way nor were they probably born with the "attraction" to murder. They probably had certain genetic tendencies that made them more susceptible. Add to that negative life experiences and you have yourself a murderer.
I know that's an extreme example. I am just saying that "attraction" can develop. As far as being "voluntary," I couldn't say. It very well may not be all that voluntary. I cannot identify with it enough to form any judgement whatsoever on that.
