First of all, it’s important to distinguish between pedophilia, sexual activity with children and sexual abuse towards children and how all of these terms are culturally situated.
Pedophilia is the sexual desire towards children. From what we’ve been able to gather, it appears to be an orientation that is fixed either at birth or at a very young age and incredibly hard to alter once it’s present. It’s important to understand that not all sexual abusers of children are pedophiles, “opportunistic abusers” abuse children in the same way that straight men turn to homosexual activities in prison, more out of a lack of other options than any real desire. At the same time, while reliable information about this is hard to gather due to how sensitive it is as a topic but there appears to be a sizable contingent of pedophiles who have no desire to practice sexual activity with children. As far as I can tell, although I’m far from an expert on this, pedophilia is reviled the world over, even in countries in which regular sexual contact with children occurs.
On the other end of the spectrum, it’s important to distinguish between sexual activity and sexual abuse. In the West, it’s taken as an article of faith that all sexual activity below a certain arbitrary age must in some way involve sexual abuse and that’s certainly how the legal system treats it but there’s also a degree of convenient fiction that we’ve adopted with this approach (I think we can all agree that two teens who are barely below the age cutoff, sending nude selfies to each other involve imperceptibly minimal levels of abuse).
For example, the Etoro tribe of Papua New Guinea believe that young boys must ingest the semen of their elders daily from the age of 7 until 17 to properly mature and grow strong. In the West, this is considered a sexual act but is this even considered a sexual act amongst the Etoro people? I’m not sure, having never met an Etoro but I would be willing to believe they regard it as non sexual behavior and, therefore cannot be sexual abuse. It would equally as absurd to them as suggesting to a westerner that they are sexually abusing a baby by breastfeeding it because adults suckling on a breast is considered a sexual act in the West.
For many cultures, the notions of both sexual acts and sexual abuse differ significantly from that in the west. While descriptions of Bacha bazi in Afghanistan certainly sounds abusive and I’m willing to grant that it’s an objectively deplorable practice, I’m not certain if can be framed as sexual abuse.
Children of every culture, in every age have been subjected to abuse for a myriad of reasons. Even in the west, is forcing a child to work in a restaurant so you can support your family abuse? Is a football coach forcing kids to run until they puke abuse? Is preventing a child from hanging out with a “bad kid” friend abuse? Is physically disciplining a child abuse? Is not providing a child with every available educational opportunity abuse?
Often, we conveniently define as “not abuse” all the practices that we happen to personally participate in. But under that same framework, it’s possible to see how Afghanis can justify Bacha Bazi for a plethora of reasons that make it ok for them, even if it’s objectively hurting the child.
On a completely separate note, there is a vast world of difference from sitting in an armchair and pondering what would be the best path for a child and being situated in the real world and having to choose between multiple objectively deplorable options and trying to figure out the least worst. I don’t think there’s any significant population of people who are happy that they have to maim children beg. But when the choice you perceive is having your child starve to death or be maimed so they can beg enough to eat, it’s hard to confidently declare that you would never maim your child in that circumstance unless you’ve personally had to make that choice. I think a lot of the deplorable circumstances that we see children under, including child prostitution and bacha bazi are made under these constraints and that the far more productive path of action is not to judge those actions but to work such that people never have to face those choices.
