+Vigano is retired and, at present, his actions amount to writing letters, e-sermons, and virtual conference videos. He doesn't hold any public office so kinda hard to censor him. Plus, I doubt he would listen anyway. He's on new-rome's blacklist for trying to expose Francis' pedo network. He has nothing to lose at this point.
+ABL was running a seminary. He had to play politics with new-rome to not get it shut down.
It's interesting how the history of the SSPX isn't really known anymore. Rome withdrew canonical approval for Econe and its accompanying institutions in 1975. Rome expected that Econe would then be shut down, but +ABL ignored Rome and kept Econe going. +ABL then began a series of appeals to Rome, which were all rejected.
+ABL was then suspended in 1976.
Pope Paul Vl wrote to +ABL in June, 1975. Here's the letter:
"Dear Brother,
It is with sorrow that we write to you today. With sorrow because We appreciate the interior anguish of a man who sees the annihilation of his hopes, the ruin of the initiative he believes he has taken for the good of the Church. With sorrow because we think of the confusion of the young people who have followed you, full of ardor, and now they find themselves in a blind alley. But opur grief is even greater to note that the decision of the competent authority--although formulated very clearly, and fully justified, it may be said, by your refusal to modify your public and persistent opposition to the Second Vatican Council, to the post-conciliar reforms, and to the orientations to which the Pope himself is committed--that this decision should still lend itself to the discussion even to the extent of leading you to seek some juridicial possibility of invalidating it."
We can see from the above how the modernists then hated tradition, and strove to stamp it out, but +ABL kept going. He didn't just use words as +Vigano does. He did something concrete.
I find it odd that +Vigano, who is fairly new to Tradition and never defended it before his rise to trad stardom 6 or so years ago, is now the spokesman for so many trads. I find his communications rather droll in comparison to the communications of +ABL, but if some here find him to be an amazing defender of Tradition, that's their choice.
