Schori's most bottom line error is she clearly does not accept creation as FALLEN, a very fundamental Christian concept. As a thorough going evolutionist though, I'm sure she see's Adam and Eve as purely mythological, and hence the Fall of man (and creation...) as fiction as well.
Unless one understands we live in a fallen creation, one cannot properly understand the world at all...with its mixture of very bad and very good.
The frustrating thing is even given her worldview, its folly to consider inherited issues as automatically good, or a part of affirming "creation is good." We all know nearsightedness or an affinity to heart disease or cancer are inherited....but NOT a part (except in His providence) of God's "good creation." Problems we inherit are things to be corrected...and this would include things like perverted sexual desires--if they were ever able to be proven to be inherited.
Bottom of it all is folks like Schori, for whatever their reasons, have chosen to call perversion good--and they simply flounder around seeking for rationalizations to justify their choices.
