There very well could be, I'm sure there's no shortage of them that will never be found out, and I'm sure that number is petrifying. BUT, that still doesn't rationalize people trying to redefine words so that they can make things mean what they want to fit a context that isn't there, simply to suit their needs. Just like free speech, you have to take the good with the bad.
Pedo's are wired wrong, theres something literally wrong with them, nobody would chose to be that, thinking otherwise is no different than people thinking you can "re-educate" gay people into being straight. Simply not gonna happen. If some basement dwelling pedo gets off on some cartoon and that keeps them functioning normal in society, while no children in real life are harmed, good luck arguing against that. Only a person ignorant to reality tries to make the reverse argument that doing so so how condones pedophilia. NOBODY other than other pedo's are ok with how they are.
