Earlier quoted context omitted.
Postmodernists think that being upset about someone's personality changes the very fabric of spacetime. "If he's mean, he must be wrong." That's hardly the case.

“Postmodernity is said to be a culture of fragmentary sensations, eclectic nostalgia, disposable simulacra, and promiscuous superficiality, in which the traditionally valued qualities of depth, coherence, meaning, originality, and authenticity are evacuated or dissolved amid the random swirl of empty signals.” ― Jean Baudrillard

"There is an objective natural reality, a reality whose existence and properties are logically independent of human beings—of their minds, their societies, their social practices, or their investigative techniques.
