"This suddenly made me realize that the Episcopal Church was essentially nothing but a protestant church all dressed in Catholic clothing with each church being able to do as they wished."
An ignorant and insulting swipe at Protestants.
Not necessarily, actually. Traditionally, the Anglicans have held that they were really "the Catholic Church in England" and "just as Catholic as the Romans". They invented the term "Roman Catholic," in fact, because they said they -- the Anglicans -- were Catholic, too, just not "Roman".
I remember when I was married in the Episcopal church (1988) the (Episcopal) priest referred to me (in my presence) as "a member of the Roman Church [sic]". (Notice: I'm a member of the "Roman Church", not the "Catholic Church", and not even the "Roman Catholic Church". Would it have been okay for me to ask him how long he'd been a member of the "Cantabridgian Church"?)
So maybe it's not an "ignorant and insulting swipe at Protestants" but an angry and justifiable swipe at Protestants who claim to be Catholics, but are not. John Henry Cardinal Newman said something very similar about the CofE when he converted.
