Does it make sense to split off between neo-SSPX and Resistance? They're becoming distinct flavors of R&R, just as sedeprivationism and sedevacantism have separated somewhat. One group wants to work with the Counciliar establishment and seeks integration while the other remains firm as a "sign of contradiction".
By the way, after Archbishop Lefebvre wrote a letter to JP2 in 1979 seeking recognition within the Conciliar establishment, then-Father Guerard des Laurier wrote him a letter telling him that it was wrong to place the Tridentine Mass alongside the NOM, that Tradition must remain a sign of contradiction against the Novus Ordo. In a sense, Father Guerard was the original Resistance member.
