I've long been of the perspective that arguing about whether sexuality is genetically determined or otherwise involuntary or whether there's an element of choice involved is a bit of a foolish argument to bother with. To say that something is "not my fault" assumes that there's fault to be had. Sexuality isn't something we should be apologizing for regardless of where it comes from. The other major issue I see here, something that conforms to a sort of postmodern perspective on truth, is the premise of the headline. It shouldn't matter what the sociological consequences of the truth are. If it's simply not true that sexuality is biologically determined (which is not, by the way, necessarily the same as being genetic) then it doesn't matter if it's a "dangerous" idea or a "safe" idea. The same is true if it is true. Our focus shouldn't be on looking for an ideologically acceptable answer, it should be on looking for an accurate answer regardless of the political landscape.
