Then you could add the environmental factors beside the pretences of work, such as them not knowing you well enough, or fearing that they are in a public space where any sign of apparent weakness might jeopardise their social position indirectly. You then pointed at the multiplicity of perspectives on any given issue and how at the social scale no one can claim that one opinion is superior to all the others, as there is no objective benchmark, no perfect scoring system, by which to arrive at the undisputed winner and to rank opinions accordingly with no bias at all. I want to have your take on social media, couched in terms of the environmental factors you mentioned and this distinction between rhetoric and dialectic.
