I wondered about that too, but I don't think jordanz meant to imply that all Catholics fit in those 3 "tidy boxes".
Quite right. These classifications aren't "tidy boxes" but rather very vague ideological (or an-ideological) ranges.
For example: within the "traditional Catholic liturgical right" there are many shades of conviction, from those who would be content with celebrating the Novus Ordo ad orientem, with some Tridentine ceremonial, and some Latin, all the way to crypto-sedevacantists who will disparage Paul VI at any turn and question the validity of Pius XII's reformed Holy Week. Even within the "apathetic" camp there are those who lean to the "left" or "right", but often have other pressing pastoral concerns which mitigate a sharp focus on liturgical concerns. At the same time, all of these sentiments can overlap depending on circumstance and individual issues.
Even in my "home" parish in the United States, the pastor and priests have made concessions to their sincere liturgical convictions. They offer at least one Mass on Sunday versus populum
and with a lone layperson to minister a consecrated chalice (most parishioners beeline to the altar rail anyway). I strongly suspect that the clergy of the parish would prefer to not make any accommodation to lay ministers and Mass celebrated facing the people, but I also suspect that the bishop has requested that at least one Mass feature these innovations. The malleability of these ideological categories is also contingent on external pressures.
