What do you mean by “Traditional Catholics”? Are you referring to those who hold to pre-Vatican II beliefs?
There are no “pre-Vatican II” BELIEFS, unless you’re talking about the world being flat or something.
Sometimes those who prefer the pre-Vatican II Mass (the Extraordinary Form, aka “Traditional Latin Mass”) are called “Trads.” I’m talking about real Catholics here. SSPXers are not yet fully reconciled. Here’s a rough breakdown:
Progressive Catholics (actually heretics, tend to be liberals).
Mainstream Catholics (go to a “regular” Novus Ordo Mass and are pretty much clueless about history, theology, etc. This is the group that supposedly “elected” Obama).
orthodox Catholics (small “o” - true to the Faith and believe it).
Trads (same as orthodox but love the old customs, Latin, and sometimes veer a bit into confusing customs and doctrine).
SSPX - think they are Trads but are out of line, meetings ongoing with the Vatican to get them to shape up.
OK, I’ll sit back and wait for the attacks...
Since, I don't have an exact definition of "Traditional Catholic," I'll refer you to this wikipedia page, which sums things up pretty well.
