That's not what they're saying. They're saying, "There are no doubt some isolated incidents, but if it really was that major, we'd know about it. There would be so many victims talking about it and surely, the media, while biased, isn't corrupt enough to hide something of that magnitude." They do not believe children are being mass raped over decades by powerful people and approve of this. The dam hasn't broken yet.

Correct, their interpretation is even more mundane and middling than OP suggests. Which is still inexcusable logic.
