This article barely seems to use critical theory (do you mean critical race theory? the article is barely about race. the article falls solidly into Wikipedia’s definition of “critical theory” simply on the basis of its overall topic.)
For better or for worse, “intersectionality” here seems to mean primarily acknowledging that more than one independent variable exists that may affect privilege or ability to be easily harassed and that the effects of these different variables are nontrivial. I do think the article could have been slightly clearer by avoiding uses of the word “intersectional” and its derivatives, but the article actually seems pretty good at explaining what it means.
