LOL I'm sede - and unfortunately it's funny how that works both ways (is it sinful to read articles put out by the SSPX?) From my viewpoint, either side is fine so long as it conforms to the true Catholic faith - obviously there are theological differences between the two sides, but I really think both sides are trying to lead the faithful to God - I don't think of them as being two different religions (like I do tradition and the Novus Ordo). I know that this would cause me to be accused of opinionism, but in my defence I have to say I personally know far too many good, good priests on both sides to think that reading their work is sinful purely because of whether or not they are SSPX or Sede. If it is sinful then there are a lot of priests on each side that aren't doing their jobs in converting the "heretics" on the other.
