I have never read anything by any of those Popes that said signing "We resist you to your face" as a public statement one would withold obedience to the Pope was permissible but Vennari signed it. I gues that is Neo-traditionalism.
It is clear to me (I used to subscribe to CFN) that Vennari is a crackpot who went to World Youth Day (does he still think of himself as a youth?) with an agenda not as a disinterested journalist.
He doesn't distinguish bewteen his criticism of the Pope and those that arranged for the music, activities etc. No need to in his crabbed, bitter and insane world. The Pope is to blame for everything.
This is just more enmity and envy from a crank who pretends he is the measure of all things Traditional.
