Ratzinger said the like, and the same applies to obeying the OT magisterium, dissent from which was a capital offense, (Dt. 17:8-13) as well as to civil courts, to which general submission is also enjoined.
However, you are confusing what must be allowed, if fallible (and can apply to pro-choice Caths), and what is required for faithfulness to the RC church, which (imaginatively) claims protection from (at least) salvific error. Thus citing conscience (as Luther did) will not make you an obedient RC in her sight.
I have every right to disagree or have an opinion about the Pope, bishops, etc. That does not make me a “dissident,” as you say, it makes me a discerner. I’m not going to explain myself further to someone who isn’t even Catholic.
