I don’t think you are the least bit nuts - I am sure that the church was infiltrated. Read the book “Aa- 1025 The Memoirs of an anti Apostle” by Carie Carre, a French nun.
Also read Malachi Martin’s books, especially Windswept House.
The Novus Ordo distortions to the liturgy were deliberate and proposed to weaken the faith - and they were successful.
I attended my first Latin Tridentine mass about 10 years ago and realized that all of the masses I had attended prior to that were pale imitations. I was born in 1960 so basically just remember the Novus Ordo - so this is not nostalgia - this is reality. I was actually angry that I had been denied my inheritance of witnessing the true mass. I felt I had been given stones instead of bread. And then the glaring doctrinal weaknesses and pop psychology that passed for catechesis - sorry to get started ...
The Latin language is precise, orderly and every word serves its logical purpose and it should not have been messed around with.
Sorry if I seem to rant - I am always pleased to find a kindred spirit and so I get a bit worked up. So many don’t get it. I am not a sedevacantist - I do believe the new mass is valid - but barely sometimes. The smoke of Satan had entered the Church, as one of the post conciliar popes pointed out. Satan won’t prevail, of course, but these are difficult times indeed.
The creators of the New Mass had the fault of reformers given their head. They totally lack empathy with others, they don’t know when to stop but indulge every craving. Besides, they wanted to make it as much like the Lutheran service as possible, or at least so it seems. Half-baked ecumenism. A few bows to the Easter Churches, but few, oddly enough, to the English liturgical tradition.
