That it can, particularly when the interlocutors are primed to perceive moderation as weakness or insecurity.To elaborate, some harsher forms of criticism are sometimes more effective communication. Too much soft-pedaling can lead to confusion.
Edited to add: Of course respectful communication is far better than the alternative. But it is not always truly available. I sincerely believe that there are frequent real-life situations where it is necessary to establish hazardous, disrespectful communication before respect can be pursued.
People can and often do refuse to perceive each other. And in those situations it can be necessary to sacrifice harmony and respect in order to ward off even more harmful stagnation.
It is an interesting tangent, come to think of that: how intensely disrespectful the insistence on isolation and lack of communication can be.
