I replied as follows:
There is no comparison. St. Ignatius of Antioch began using the word "Catholic" early in Church history, and it caught on as a word that describes and even names the Church and the Faith of the Church with the Universal Consensus of Antiquity. The word "Protestant" is neither its equal nor its opposite, having been coined late in Church history. The point is merely this: Anglican usage of the word "Protestant" actually speaks of a goal that is very Catholic.
The problem with Anglo-Catholic reaction against the "P" word is that it is counter productive, and is so in different ways.
1. Arguing, as some try to do, that the English Reformers were not Protestants, automatically gives ground to the Roman Catholic polemicists, by accepting their partisan and inaccurate definition (which definition carries false history). The argument itself is unsustainable, if not patently absurd.
2. Others argue that the Reformers were Protestant, accepting the Roman definition, using the word negatively as if it were the word "communist." The result is they fall into the Roman trap, and begin to doubt Anglican validity.* They try to distance themselves from the Reformers in England, either by rejecting Anglican doctrine, trying to argue that it was bad, but not bad enough to render Orders invalid (this bunch are concerned only with this one point). Or, they rely on the Dutch Touch to set things right.
No wonder such "apologists" cannot help but leap into the Tiber, and cannot do anything but lead people to Rome, instead of into Anglican churches. They have no knowledge and no foundation. They possess a wealth of ignorance.
The realistic approach would help many people remain Anglican. Accept the English Reformers for what they were, and learn why their doctrines were perfectly acceptable in true Catholic terms, true Catholic terms that are older than the distortions of doctrine in Roman innovations and errors. The standard we use in The Continuum is the Canon of St. Vincent of Lerins, Universal Consensus and Antiquity (before anyone reacts, that standard automatically gives the greatest weight to Scripture, which ought to be obvious).
*Of course, as a priest in the Anglican Catholic Church, my usage of the word "validity" is very conservative and traditional. We are not in communion with the Anglican Communion; we continue Anglican doctrine and Orders without modern corruptions.
