I don't deny the SRA of kids and pedo stuff, but I question how widespread it really is. There is certainly a lot of "evidence" that it's huge, but I wonder if it isn't black propaganda to serve a number of ends like getting people passionately engaged in the counterinsurgency citizen journo movement and also the threat of being so well done as to potentially be enough to frame a number of people in untrue crimes.
Just a thought.
