A Traditional Catholic is defined as: a person who deals with the Crisis in the Church by leaving the Conciliar Church and seeking out true (valid, properly formed) priests and true Sacraments/Mass (the Tridentine Mass) and not asking anyone's permission to do so.
This is my honest attempt at an accurate, objective definition of what a Traditional Catholic is. The definition is as inclusive as possible, yet captures the essence of Traditional Catholicism. Whatever the best definition is, it would have to apply to Catholics from 1970 to the present, since the Traditional Movement has been around that long.
For example, in the earliest days, Traditional Catholics existed all over the world, but none of them were concerned with permission from Rome. The first step was people walking out of the Novus Ordo, never to return. They instinctively gathered (like eagles) around any priest who wanted to stay Catholic (Traditional) and offer the Tridentine Mass. They knew that the salvation of souls came first, and that the Catholic Church herself supplied any jurisdiction that was needed for things like confession, marriage, etc.
Furthermore, Traditional Catholics all believed that the Mass was important. That is why they drove long distances to be where the Tridentine Mass was. They knew that the Catholic Faith was a habit of life, and that raising children Catholic meant having a place to attend Mass on a regular basis, even if it was not in an ornate cathedral building.
Therefore, I don't think I'm being too mean or sectarian by excluding Home-Aloners and attendees of the Indult (including Diocesan and any Roman-approved group).
In this context, by "Home Aloners" I mean those who hate the Novus Ordo and Conciliar religion, and have nothing to do with it, but they also believe that the Traditional Movement is not legitimate. So they fail to "seek out true Mass and Sacraments". They ignore all the valid, Traditional priests and Masses available. They are aloof from the world of Tradition, even if they seem to oppose the Novus Ordo with all the Traditional Catholics.
Indult-attendees should be excluded because they believe that permission from Rome is useful or even required, in order to resort to the Tridentine Mass and pre-Vatican II Catholic Faith. This also goes against the basic tenets of the Traditional Movement as it has always existed. Any real Traditional Catholic knows that we have a right by our Baptism to sacraments/Mass which are 100% sure and priests that are 100% sure. The sheep of the flock have a right to be fed good nutritious food, not dung.
