There are very few organizations that have as broad a reach as the Roman Catholic Church. For almost 2000 years, it has expanded its influence into every part of the world. In some ways, it has been a force for positive influence. In others, it has been a force holding people back and keeping them down.

As a global religious organization, it puts itself forward as the voice of Christianity. All of the questions in my OP are related to its activities around the world that do not work in positive directions for human rights. Why should anyone fail to point that out when there is an opportunity. People praise Bernie Sanders for speaking out for his principles. This trip to the Vatican gives him another opportunity to do that. I hope he does exactly that.

Refinement is an excellent thing, as is decorous behavior. However, etiquette is only a guideline. it should be honored when it is appropriate to do so, but not in a way that keeps a person from stating a position. Bernie Sanders is not subject to any Roman Catholic rules or dogma. He has no reason to be subservient to its rules in any area. He will not kiss the Pope's ring. He should speak frankly and honestly. That can be down without any serious breach of Vatican etiquette. Any statement or question can be made in a respectful but honest way.

The Pope has no authority except with respect to followers of his particular sect of Christianity. None whatsoever. He is a religious leader with some political heft, but that is all. One can call him to account at any time. He may not respond positively, but of what matter is that?
