So its the Episcopal church not the Anglican church going off the rails completely ? Or is there overlap ?
Depends a lot upon terminology and location, among other factors.
Just think "Christian church going off the rails" and realize that you're depending upon self-definition of "Christian" and you might understand the problem. The only clear point is that the Episcopal church (PECUSA/ECUSA/TEC) is off the rails, but the term "Anglican" covers a broad range.
