I am perfectly willing to tell someone that something they just said is offensive.
That is fine, for as far as it goes, and how far it goes depends a good deal on context. For many years, i worked for a state universities civil service system. What i often ran into was an initial incredulity that anyone would think differently than "I do," and actually have a cogent argument. PhDs who are tenured professors often, truly, are not at all used to having anyone disagree with them, except for their peers (i.e., other tenured, "full" professors), whom they simply dismiss as pompous jackasses. But among those who were assistant or associate professors, or graduate teaching assistants, there was much livelier discussion, and a good deal of healthy debate and disagreement.
But when it came to the mere undergraduate students, everyone drew a line--students are not to question the instructor, no matter what their relative status among themselves. There always seemed to be a hierarchy of tolerable dissent, and undergraduates were the serfs in that scenario. There was one tenured, "full" professor, who was held in contempt (but a wary contempt--you didn't want to get on his bad side, because he was devastatingly brilliant, and could rip you up if you were peddling BS) by the other professors. He had only published enough to justify his position, and all his publications were text books. But he wrote scads of papers, and they were almost all concerned with pedagogy. One of his papers,
Let the Student Do the Talking, was brilliant, and he practiced what he preached. He was an expert in comparative English/French grammar, and he had published a standard text on French grammar for speakers of English. So i took his undergraduate course (and got laughed at for it), and really learned something. He hardly ever spoke in class--if someone had a question, he'd go around the room until he found another student who could answer the question. If he went all around the room, and no one answered it, he'd stay on that question until the students worked it out for themselves. Among the undergraduates, he was very popular, and it was hard to get into his classes (i was only able to sign up because professional staff were allowed to take "professional development" courses and were guaranteed registration rights--plus, he and i got along so he let me in without quibble). Many years later, i read his obit in the
New York Times, which was a shame, but was also a measure of the respect in which he was held in the academic world, even if his immediate colleagues were snotty toward him.
I found much the same in the years i worked in hospitals just after i got out of the army. Doctors (a lot of them, perhaps most of them) do not accept that anyone will question them. Nurses and other professional and "ancillary" staff, however, were well-educated and intelligent, and you could get lively discussions. What was silly about it is that many doctors know almost nothing outside their profession. There was a radiologist at one hospital i worked at who had a national reputation for his skill in reading x-rays, and who was an ornament to the hospital. He was also obsessed with the flood account in
Genesis, and claimed against all the evidence that geology confirms the account. The Tennessee River is deep and fast in its eastern range, and has carved deep valleys in the hills. To most geologists, the strata revealed provide excellent evidence for the history of the river, which is tens of thousands of years old--but not this joker. In fact, he claimed the strata were evidence that sediments had been laid down by the flood, and he would become very angry at anyone who questioned him. Years later, i was amused to read an anecdote of Carl Sagan. He was at a party, and speaking to a professor who was a specialist in ancient texts. Sagan commented that he had always known that Immanuel Velikovsky was full of poop when it came to astronomy, but that he had been impressed with Velikovsky's knowledge of ancient literature. The professor Sagan was speaking to said that he was impressed by Velikovsky's knowledge of astronomy, but that he (Velikovsky) obviously knew nothing about ancient literature. It seems that highly-educated people who stray outside their area of expertise often believe the most errant crap, but you had better not question many of them (perhaps most of them), because they are not accustomed to disagreement. Of course, i couldn't speak to how this works with highly educated people who work outside of universities or hospitals, where their every word is not holy writ.
Years later, i relocated to Ohio, and set myself up for a manager of small business. I was modestly successful, and i consequently came into contact with a lot of people on construction sites, and people in building trades and other skilled laborer professions. They know their own fields well, but they often know little else beside that, and don't enjoy being told that they are ignorant, or that they are wrong. I reverted to the default position i had learned as a child, and avoided discussions of religion or politics. My brother many years ago worked for a large manufacturing corporation in one of their factories in the evenings while he was getting an engineering degree. To the guys on the assembly line, he was the "college boy," and an oracle on all things outside their everyday experience. One group with whom he took his breaks included a Jehovah's Witness, and the other guys were always on his case about how "stupid" his religious beliefs were. One evening, this guy brought in a concordance--a bible with English on the left-hand page, and the "original" Greek on the right-hand page (i will avoid a discussion of the unreliability of the "majority" text Greek versions). So when my brother came into the break room, one of the guys handed him this bible and asked him what he thought of it. My brother looked at it and said something to the effect of "Oh yeah, that's a concordance." To which the other guys smiled triumphantly, and one of them said, "See, i knew it was bullshit."
I'd say the advisability of lively discussions of religion or politics depends a great deal on the social context in which one finds oneself.
