Williamson is merely telling Hewko to buzz off, by stipulating a condition he knows Hewko will not accept
If so, then this is a horrible lack of leadership skills and an immature way of resolving conflict. He should have kept the debate focused on matters of principle; instead he allowed it to veer off course, into matters of opinion and speculation. No one can win such a debate.
Fr Pfeiffer is 100% insane, while I think Fr Hewko is sincere but too extreme in some areas (which is rather common in Trad circles). But +W's response to this situation has hurt his integrity by not addressing the key areas of dispute. Had +W known such letters would be made public, he may have responded more politically, but in this day and age, how do you NOT expect such to be made public, especially when Fr Hewko often publicizes many things? +W needs a PR manager, because this is just messy.
