Actually, I think Jack does, and to some extent, that is the problem.
As for as the Marian Doctrines, there is plenty of evidence in Luther’s Works that he personally believed in the Immaculate Conception and Assumption, as do many Lutherans today. So arguably, belief in those doctrines is not necessarily “un-Lutheran.”
As for the objection to indulgences, (and I will not say this necessarily applies to Jack) a great many Lutherans are still fighting against and reacting to the Council of Trent and ignoring Vatican I and II. Most (not all, but most) Lutherans also object to a Magisterium which allows something (like indulgences) taught by documents of the Magisterium to be de-emphasizd, but never cancelled, since that would essentially deny the infallibility of the Magisterium. Jack and other Lutherans seem not to realize that the Catholic Church of Today is not the Catholic Church of Martin Luther’s Day. The Church has changed since then.
As to objections to clerical celibacy, that is a discipline. It is backed up with a lot of theology but it is neither dogma or doctrine. There are in fact married priests in the Catholic Church, in the Uniate Catholic Churches outside the U. S., in the Eastern Orthodox Churches, etc.
Many Lutherans, while denying an infallible Magisterium treat the confessional documents in the “Book of Concord” as if they were infallible (because - quia - they are “trustworthy witnesses to the Gospel,” and have remained so since their writing; making the Book of Concord in effect a “paper Magisterium”.
