The only good pedophiles are the ones horrified by their fantasies to never carry it out and they keep themselves away from being tempted.
Your point is exactly what he said. Not supporting this loon, but no one reads articles it seems.
Let me start by saing I think Dan Savage is a vile bully. However, if you read the article, I think that is what he is saying. The "good pedophile" is the one who never acts on his urges and keeps himself out of situations with kids. Savage buys into the idea that the sex drive to like children is some type of chemical or physiological imbalance and not a choice. And that this imbalance can be treated and dealt with by not putting oneself in the wrong situations (like babysitting kids).
The irony of ironies is that the same can be said of homosexuality -- that it is some type of physiological imbalance that can be treated and dealt with by not putting oneself in tempting situations. Of course, Savage would never give that advice to a gay man because homosexuality is "natural". Then why is he giving it to a pedophile?
