That was frustrating to read alright. They went to 2 sites, neither of which I've been to, so I can't verify the story. I've heard of 7axxn, which seems to be a mix-bag, free-speech, open-discussion kind of place, where you'll naturally get all kinds of arguments and aid. The other site was strictly CP-less, and entirely about fantasy. The small amount they said about it suggests to me that it was more about love and lust than rape and pain.
If they'd done due diligence, they could have gone over to PSC (assuming it's still up). That place was fantastic for child lovers, massive userbase, healthy discussions, no CP, and most importantly, NO PEDOSADISTS. On there they could have been honest about researching, and gotten some good responses, though the staff would have been diligent in preventing personal information getting out.
I think the most annoying part is that they started with the assumption that child sexuality either doesn't exists or is always negative, and never even looked at the other side of the coin.
It's an aggravating propaganda piece. Nothing more.
