I can understand why you are upset. What I don't understand is why you are "shocked". Did you not see this coming? Does it put you in a forgiving frame of mind with respect to ACNA? Does it give you a new perspective on Anglicanism's weaknesses? Where is the tipping point for you, and is that tipping point now in view? What will you do when/if you reach the tipping point?
A bad bishop doesn't change anything. If anything, that's normal in Anglicanism and all Christian denominations. I'm surprised that you, of all people, are plugging in for ACNA.
