Common themes represented here:
Mansplaining/women’s perspective is wrong. Kotex to girls and women: WHY OH WHY are you fools so embarrassed by your periods? It’s just you being dumb, it has nothing to do with the demonstrable fact that girls and women are oppressed due to your reproductive SEX. Sure, menstruation is proof that you are indeed biologically female and therefore inferior; and also that you have FAILED the only thing you are good at — becoming impregnated. But feeling bad about that is counter productive to your buying this new product (which is the dumbest idea I have ever seen BTW — brightly- or distinctively-wrapped tampons and pads? WTF?)

PIV-centric narrative — Pathologize menstruation. See above. Menstruation is pathologized because it benefits men and male power to medically, socially and sexually pathologize demonstrable proof that a pregnancy has not occurred. Menstruation is also a reliable indicator of biological sex: in this case, that a person is a member of sex class female, also known as the defective and rapeable class. The only “cure” for menstruation is PIV (and pregnancy).
