r/PCM made the same interpretive mistake--assuming "collective" to mean "collectivist".
"...describing hatred (vs. mere dislike) towards collective entities (societal phenomena, institutions, groups), but not individuals, heightened feelings linked to the behavioral approach system (BAS; eagerness, determination, enthusiasm), which underlies a sense of significant purpose". I'm too lazy to read the article, but this to me clearly refers to groups--clans, subcultures, classes, etc.--rather than toward
the masses, members of the DSA, etc.
