You can't compare the disaster in the ECUSA with the internal politics of the Roman church. We have seen the ECUSA dwindle in numbers due to bad faith clergy from the early 1970's.
The ECUSA is a grassroots organization without a strong administrative center like the vatican. When the common culture tanked in the 1960's, the ECUSA lost its moorings and began grabbing at straws. They doled out millions of dollars to radial organizations (the black panthers), admitted female and gay students to the seminaries, and adopted a secular legal framework of internal laws for dealing with pure heresies such as the ordination of gay priests.
In 1996, the year long study of what to do about the ordination of the first gay priest resulted in a concensus of the US bishops that no legal framework was in place to deal with this subject therefore, no action should be taken.
As a fish rots from the head - so did the ECUSA.
I was not comparing Catholics and Anglicans in that sense. I was suggesting that the left will attack Catholicism using the "model" they developed when they destroyed the Episcopalians.
