I was raised Quaker, and in theory one of the core tenets of Quakerism is that uncomfortable honesty. Trivial example: refusing to swear on the Bible because that would imply that you might not be honest when you hadn't just sworn on a Bible.
I have found that Quakers are just as fallible as anyone else; but the subset of Quakers who really live that tenet have an unnerving and extremely peaceful unflinching willingness to comment or question on problems in a way that removes the smokescreens of social obligations. I've found it far easier to talk about anything involving money, feelings, sex, danger, beliefs, crime, fear, etc. with those individuals who have really committed their lives to only let truth come out of their mouth (even if they don't always succeed).
I was raised in the Friends culture, and find this characterization skewed. "Honesty", yes. "Even if uncomfortable", sure, often, but only literally speaking. But I've never heard a Quaker in my life extol "uncomfortable truth" in those words. Because, realistically speaking, "telling the uncomfortable truth" when declared as a principle is 99% of the time just a wordplay excuse to be an asshole or to be petty (which I assume is why I never heard the Quakers in my life use that phrase, since they tend to be not only honest, but also kind and pragmatic).
Sure, I'll concede that the common wording of "uncomfortable truth" has been hijacked by podcasters and their ilk. I just meant "the truth, even when it's uncomfortable".
This is one of the oldest trick in the book of very very dumb people who confuse "the truth" with "what they think".
I'm sure we all met that person in the family or in a new job, or at school being so proud of themselves for being "honest", and later on you discover that their honesty is not honesty, it's just "saying whatever crosses their mind unfiltered".
