Thinking abhorrent things isn't against the law. Creating a market for children to be sexually tortured is.
A few years ago I read a piece by a woman who is now a campaigner against child sexual torture imagery. One of her earliest memories was being taken to the basement of a department store as a small child, where she and another child had to engage in sexual acts, which were filmed. And that was just the start - things got rapidly darker, from there. Her parents had made her available, and they did this to her throughout her childhood in order to pay for their lifestyle. They weren't paedophiles, and never directly abused her. They just wanted the money. She was raped, from very small, most often by grown men. Her distress and pain was part of the appeal, commercially. The images and footage remain all over the internet. Her parents weren't even especially poor - just greedy and ruthless. She was made to feel responsible for the family's income.
She commented that as an adult in group therapy, her peers would be devastated over one rape, and she found this astonishing. She literally could not remember how many times she had been raped through her childhood, or by how many men. And her parents did this to her - solely for the money. It's unfathomable, but it happens, because as long as men exist who will pay to watch children being raped, people will provide their children to be raped for commercial gain. That woman would never have been abused, had there been no market of men wanting to consume the footage. People like Eric Joyce.
That is what people do when they access this. They encourage people to rape and sexually assault children for profit, or to make their kids available for such abuse. It's a commercial transaction as well as paedophile criminality. And it's funded by the remote participants. They've supported a market - and the cost can be counted in raped and trafficked children. They're not solely thinking abhorrent thoughts, and it's not without impact on child victims. You might as well argue that meat eaters who don't personally work in abbatoirs are vegetarians.
Eric Joyce is absolute fucking scum, and he belongs in jail. That's not the judge's fault. As has been said, there are judicial guidelines. But as a society we don't take it seriously enough as the human rights atrocity it is. This is an industry that trades on the mass commercialised rape of children. Anyone engaging in it, in any way, is complicit. And the criminal penalty should reflect that fact.
