Yes, it happens. But you haven't proven anything about the most important measure by which to compare religious organizations like Christian churches with other non-religious organizations: the rate. You're kind of behaving as if you've proven that Christian churches abuse at a higher rate, but you have not proven that! The most reasonable assumption in the absence of evidence is that children suffer at the same rate regardless of whether the organization is religious or not; under this most reasonable assumption, there's no reasonable basis upon which to focus your fury on religious organizations because in reality and contrary to your unreasonable hyperfocus on them, they're just like all others.
