I will assume you are not reading the Church documents, nor the Church explanation as to why the Council was called, and it would sound as if you may not have read the 16 documents.
Your comments about the Protestant observers would be hilarious if it were not based on pure, unadulterated speculation and repeated lies. There was nothing in the Council that was aimed at “Protestantizing” the Church, or meeting them “halfway”.
It was based significantly on the fact the Trent, in reacting to the multiples of heresies at the time and previous to the calling of that council, reacted in large part in a minimalistic way; it in essence defined the doctrines and practices which were at the minimum necessary to counter the Reformation. In that, it did a great job; but while it most definitely needs the doctrines of the Church clarified, doctrines are not faith. they guide and shape the faith, but they are not faith. And the Church spent then next 400+ years approaching its mission of spreading the Gospels, by falling back on stating doctrine.
Vatican 2 had no intent on getting rid of doctrine or minimizing it; it intended to take a different approach to evangelization.
Your examples show an inability to distinguish what was intended solely as a broad brush picture, for example, of liturgy, and you see the Constitution on the Sacred Liturgy as setting out the disciplinary rules of it, rather than as a document intended to guide forward. You see in in absolutest terms, and it was never intended as such
I can appreciate you may not like the liturgy today; I suspect that you would not like the liturgy of the Church in, say 600 AD either. Liturgy was most definitely not hadned over to the laity; the GIRM comes straight from Rome. If bishop does not fulfill their role in guiding the liturgy, laity on the parish level might have some influence on liturgical matters; if the bishop does what he is supposed to do (and the vast majority do) then whatever minimal room for the laity’s (name removed by moderator)ut is allowed, and the rules are followed. Given there are over 17,000 parishes in the US, please do not provide me with anecdotal commentary; I am familiar with what has happened over the last 67 years (I am 72); I am also aware that in most dioceses, most Masses follow the GIRM.
It is hilarious that you think removing Latin was eliminating the unifying elements of the Mass; given that there are something like 23 eastern churches/rites within the Catholic Church, unity has never in 2000 years meant uniformity. I have attended Masses in Vietnamese and in Spanish and within the Roman rite, there is unity - and a high degree of uniformity, since they all, in the US, follow the same GIRM, a point with which you seem to be unfamiliar.
