I don’t see how they can protest CANA. Surely the Episcopal church over the centuries helped fund Anglican missions and churches in Africa (there are several hymns in the 1940 Hymnal that make reference to this). And I bet our church ancestors didn’t ask permission to do this either.
TEC would argue that in such cases there was not already an Anglican presence in those regions. Orthodox Anglicans (if they were to ignore continuing Anglican Churches such as the ACC or the APCK) might argue that the same is now the case in the US.
