Offence
In general, LinkedIn comments are a weird mix of politeness theater and stealth competitiveness.
Because it’s a “professional” space, people usually cloak their offense; instead of saying “I’m offended,” they might say things like “Interesting perspective – I’d encourage you to reconsider…”.
Usually direct expressions of offense are rare; it’s usually indirect, judgmental, or couched in “advice.”
There’s also a perceived social penalty for looking too emotional, so people filter their offense into “constructive feedback” or “disagreement.”
Or more commonly they just say nothing.
People come to LinkedIn for validation, not confrontation.
