Because it’s valuable to deconstruct any concept that is held without a clear reason. It’s far more important to know why you believe or feel what you do than just knowing what you feel or believe.
I’m not expecting to convince people of my position, nor to have others change their positions based upon said deconstruction, but it’s worth raising nonetheless.
If attraction can be socially programmed (as it so very obviously is), then it can similarly be deconstructed. The first step to achieving that is questioning the motivation for attraction beyond “that’s hot”.
