I think you load the question by having “truthful” parentheses in context of “degrading.”
It loads it with your own subjective moral opinion. Because who are we the fact check or verify what is truth?
To answer these types of questions about online communities we just need to take a lesson from IRL communities.
I mean if we take what you ask at face value some of us might imagine online social media with its IRL analog as a giant frat house.
But there are lots of problems with that.
Nothing is inherently wrong with some sensitivity (safe spaces) and nothing is too bad with harsh truths.
But it is how we act on these and handle conflict with our fellow community member that defines most problems.
If it really is a “truth” And you want to communicate that rational objective fact (from your perspective) Then it should be done without “degrading” anyone. Because most of the time it’s just a personal attack regardless of the content.
