Can it ever be said a condemned proposition is nonsensical?
Yes, it is a condemned proposition, but the proposition doesn't even make sense.

To say within one's heart that they do not intend to do what the Church does, it would follow that no action would be performed.
What does the Church intend to do in regard to baptism? The Church intends to pronounce the words and pour the water.

a wish or inclination not strong enough to lead to action.
This is not what is being discussed:
All sides acknowledge there is at least a PRESUMPTION of validity when proper form, matter, and minister are present.
Where things begin to break down is where the minister does in fact form a contrary intention to not do what the Church does.
Ladislaus says the sacrament is still valid anyway (against the popes and theologians), even if such a contrary intention were present.
The Siri-ists (like our new anonymous troublemaking antagonist here) say one can go against the presumption of validity even in the absence of any exterior manifestation of that contrary intention. They advance extraneous and circuмstantial “evidence” completely disconnected from the performance of the rites as evincing positive doubt regarding intention (when it is nothing of the sort).
A disinterested and dispassionate reading of the popes and theologians shows both to be in error, with the truth being that on the one hand, it is certainly possible for a wicked minister to perform the rite with proper form and matter, yet form an invalidating contrary intention, and on the other hand, to acknowledge that, despite that concession, the presumption of validity remains in the absence of any exterior manifestation of said contrary intention (as is the case in the Lienart/Lefebvre matter).
Add to all this the uncertainty surrounding the Lienart story (which would make the whole matter moot in the case of Lefebvre), and the whole story of our Siri-ist friend is really just a big nothing burger, upsetting to simpler souls, but unable to withstand closer scrutiny.
