There's the academic philosophical postmodernism, which rejects metanarratives. Then there's a derived ideology taken up as the basis for a lot of Intersectional activism which can be termed "Social Constructionism." As is the case for many activist derivations of ideology, there is some straying away from the original academic version. While postmodernism claims it rejects metanarratives, like the one in Marxism, the derived ideologies share a lot of parallels in effect. They both result in opposing groups which can't effectively talk to each other, so must coerce each other by force. (Doesn't this remind you of the Intersectional "Stack Ranking" and the "Oppression Olympics?") They both effectively result in a rejection of logic. They both effectively create their own forms of obscurantist alternative "logic." The ideological effect of both Marxism and Social Constructionism is to come up with a pretext for rejecting existing standards and tearing society apart -- one which is ideologically sealed against negotiation, logic, and adaptation to evidence.
