So, FSSP ... not Traditional Catholic, but traditional Catholic (just liturgical preference, smells and bells)
As for having been on the forum under a previous name, the question becomes why you didn't come back under that old account? Was it banned? Were you trolling and wanted a fresh start? That's why it "matters".
Traditional Catholics hold that there's a substantive rupture between the Conciliar Church and the Traditional Catholic Church, that the two are different in kind, not just different in some accidents. "traditional" (lower-case) Trads don't think there's any kind of rupture with Tradition, but just some general veering off too far to the left, that it's more about implementation than about substance, and ya like dem smelz and belz (and aren't a fan of clown Masses and guitar music).
