Empirical studies have actually shown that consumers of child porn are unlikely to molest children. Those that are arrested for possession of child porn AND have a high likelihood of future molestation ALREADY had a history of molestation.

This shouldn't be surprising. Consumers of rape fetish porn are unlikely to actually rape someone, but actual rapists are likely to consume rape fetish porn. Furthermore, in countries where porn of all kinds was legalized, including child porn, enjoyed falling rates of child molestation.

The OP is making some of the same old arguments people have trotted out against porn for decades, just couched in pseudo neuroscience. The fact is, we don't understand these relationships to the degree the OP needs to justify his causal claims.
