It is interesting that Father Kings named five groups of Anglicans in the USA, but of those who have "opted out" of PECUSA/TEC he has included only those who have aligned with the global south and has omitted the continuing Anglican churches who have not only maintained traditional Anglicanism, but have done so in a Western rather than an African cultural context.
You are correct, but it was my experience i the late 70s and early 80s that PECUSA was very heavily talking down the Continuing churches, and a lot of people bought into that. (As did I -- until I encountered one of those churches for myself.) The attitude continues.
