The difference in the labels you describe actually mirror some external reality.
The Catholic Church and the various Orthodox Churches are not in formal communion with each other. This is objective reality. That lack of formal communion exists in part because the Orthodox do not think it's a good idea to have formal communion with the Catholic Church at this point. The objective reality is that the two sets of entities distinguish themselves from each other.
“Traditionalist” Catholic groups that aren't in communion with the Bishop of Rome are, well, not entirely Catholic, or in some anomalous state vis-a-vis the Church, at least in the view of the Church of Rome.
Although I'm against excluding SSPXers from Catholic Caucus threads (the pope said that the issue of the SSPX is an INTERNAL church issue), at least there is some objective reality onto which to hang the caucus label hat - their position is not canonically regularized.
But the FSSP?!?
The FSSP are NOT outsiders to the Catholic Church IN ANY WAY, SHAPE, OR FORM.
You seem to agree with this statement that I made:
“My perspective was that the caucus label is meant to avoid disruption from OUTSIDERS, not internal disagreement when there are legitimate differences of opinion within the Catholic community here at FR.”
Then, why would you exclude the FSSP or those who assist at FSSP Masses? They are NOT outsiders to the Catholic Church. What differences we may have between us are INTERNAL disagreements.

The entire point is to find a way the poster of a caucus can avoid disruption.
I was happy as a clam when the term "Catholic" included "Orthodox." And it would be fine with me if the further distinctions in post #8 were dropped or if the usual caucus posters agree that excluding FSSP was not their intent.
