I don’t know about “more Catholic than the Pope” but more Catholic than Vatican II, certainly.
You make a distinction without a difference. I note that radical "traditionalists" and radical modernists make the same error of viewing Vatican II as a rupture with the previous 1900 years of the Church.
It was not, and is not, and all the hideous abuses committed in the name of the spurious "spirit of vatican 2" are no more Catholic than the silly idea that a rogue bishop has the authority to go looping off on his own, creating an ecclesial community in defiance of the Pope.
A plague o' both their houses.
