According to Rev. Canon George Conger of the Diocese of Central Florida the answer is "Yes." There no longer is an Anglican communion in a meaningful sense. For evidence he points to the recent Lambeth Conference in which Anglican bishops would not take communion together because of the (mostly) American actions on ordaining practicing homosexuals. Also, he points to the fact that within the Episcopal Church (Anglicanism in the U.S.) conservative priests would not be allowed to serve in a liberal diocese nor liberal priests in a conservative diocese.

The future of Episcopalianism as he sees it: litigation. Lawsuits over property as parishes and dioceses disassociate.

The cause: the belief by the Episcopal leadership that God's path forward is through recognition of same-sex orientation and practice as a blessing, and the providential role the American Church is to play by introducing to the world this new revelation. Another form of American exceptionalism.
