Oh, I rather define it as a worldview where individuals are sorted into classes defined by their sexual and racial (and other, including socioeconomic) characteristics. And thinking that these groupings almost perfectly define every single persons actions and destiny.
It''s connected with the idea that anyone's success is not due to their hard work, parents, education, luck, ... but rather simply due to their belonging itself to at least some of the "privileged" subgroups, and the systemic exploitation of the unprivileged subgroups.
Really, it's just a zero sum class warfare with differently defined classes.
Of course, the exploitation is unjust, so we need some smart emphatic state rules to fix it. And thankfully, we have the social justice warriors to unconditionally serve this goal.
