I like the OP's thoughts on this matter, but I think the logical thing still is to picket. First of all, it would be a hard opportunity to pass up merely on principle. Secondly, though the WBC are crazy, there is a chance that just one of them could learn something or gain a new insight. If there is even one infinitesimally small chance of that happening, I'd still say go for it. There isn't a damn thing that we could try that IS rational that will work on them. I don't know if that's fire with fire or monsters with monsters, but it can't hurt to try now.
