Why prolong the conflict? The Oatmeal wants to move past all this. Emailing FJ is just going to cause them to be agitated and therefore continue to pursue their action, prolonging the headache. It might even be counterproductive if they can use the mass of emails as "proof" that their reputation has been damaged.

Let's not take a funny/clever retort by TheOatmeal and ruin it by being jackasses.

With honesty, what good will that do?
