Please don’t misunderstand me here. I’m not asking what the fuss is about pedophilia — that’s an easy one, I hope — but rather I’m unclear what is achieved by forcing Amazon to ban a single disgusting ebook from sale. Or, indeed, what precise harm we think will result if they refuse. It’s that other material — the truly vile and illegal stuff, hidden from public view — that represents the true threat to the fabric of decent society. And it’s that material that we need to figure out how to banish from the Internet before we start congratulating ourselves on a job well done.
