Eichmann had the attitude "superiors must be obeyed without question", you have the attitude "the magisterium must be obeyed without question". Both of you have exactly precisely the same attitude: "let other people make moral decisions for me". It should be obvious that abrogating moral responsibility is not how a morally responsible person behaves. Yet that is what you insist must be done.

Given that HV says that, according to "natural law", the "primary end" of sexual intercourse is procreation. Essentially all sexually active persons know this is untrue -- it's certainly not why they have intercourse. Worse is their justification: HV 4 says "No member of the faithful could possibly deny that the Church is competent in her magisterium to interpret the natural moral law." Which amounts to "we know this is true because we say this is true, take our word for it". Sorry, but I've given up circular reasoning for Lent. Saying this whole thing is twaddle is being kind.
