The SSPX (are you listening SSPX) is simply playing to their supporters. Show some sort of indignation (weak as it may be) but not so as to upset Rome. So many cliches here: straddling the fence, playing it cozy, playing it safe name it what you will.
The hour is late SSPX, say what you will, but there are now alternatives which will expand as things get worse. There are new times. Truth travels at the speed of a keyboard. You can't hide. It takes money to run an empire. When the money dries up, the empire crumbles. A rich inheritance will not sustain forever.
