1. The crime that utterly dwarfs all others is involving children in the making of child porn.
2. After that, the crimes that dwarf all the rest are those that provide financial or practical support to child porn makers. Consuming child porn is generally regarded as one of those, and I'm fine with that categorization.
3. I'm sorry, but violating a victim's theoretical privacy by distributing the images a little further doesn't seem to be nearly as big a deal as helping to prevent the next live video of child porn from being made.
I'm usually regarded as being pro-privacy, but privacy is not something to be a rabid extremist about. Preventing physical sexual abuse of children, on the other hand, is a fine area for extremism.
