It may be that the Scriptures concerning the elephant call the elephanteers to repentance regarding it -- my perspective on that topic is one I've argued here before the carefully crafted rules that are enforced so unevenly were written -- but as a loyal Anglican, I am obliged to follow the teachings of my priests and bishop, or go elsewhere -- and they teach me that my own obligation is to show brotherly love, compassion, welcome, and acceptance to all my brothers and sisters in Christ, without reference to the elephant.
IMO those who use the elephant to exclude are guilty of a sin themselves, and should repent of it. However, just as the above indicates, their own examination of conscience should judge that for them, not me.
