http://en.wikipedia.org/wiki/Pedophilia
The extent to which pedophilia occurs is not known with any certainty. Some studies have concluded that at least a quarter of all adult men may have some feelings of sexual arousal in connection with children.[26] One study found that professionals failed to report approximately 40% of the child sexual abuse cases they encountered.[27]
This doesn't mean that they "want to have sex with children", Darla.
Of course, most people who have such a disease are utterly disgusted by it, and would never admit it. They are also never likely to have sex with children.
The main problem is those that completely think it's OK to go out and molest whatever children they want, no matter the consequences.

I am calling bullshit on that for sure.
