You're missing the point. Some people are quick to claim that the other person is being unreasonable in a way that's socially agreed upon to be bad as a justification for whatever their thing is, whether that's being a lazy worker at a min-wage job or anything else. And of course sometimes these people don't even wait for unreasonable behavior. They will characterize "hey can you please do your job" that way because it suits them.

This is a figment of living in a culture where being right but distasteful in a variety of poorly defined but broadly similar ways effectively makes you wrong. Toward the other end of the spectrum is stuff like "I don't care if he's a card carrying nazi he builds good rockets" and other stuff like that.
