These two people are really harmless, albeit they may have decided to follow the "spirit of Vatican II" a little too closely. They are in their 60's so when they heard the novus ordo presider say things like "Everybodies a minister of the eucharist, my friend" they decided to follow that up with an "if everyone's a minister of the eucharist, why not add that everybody's a consecrator of the eucharist too".
Or maybe they took the "royal priesthood" schtick a little too seriously.
Others have mentioned that this excommunication is all nice and good and about time but they asked why pro-abort politicians aren't excommunicated. I say for the simple reason that bullies don't go around punching people who can punch back.
Or, more sinister still, this could be some form of fαℓѕє fℓαg. If a hubbub ensues, the Vatican may rescind the excommunication and subtlely slip in a big change in a small way.
