Douching is not only an anti-feminist practice pushed by male corporations on women using shame and insecurity as a weapon, but it is almost certainly dangerous to a woman’s health. And therein we find the link between the medical appliance, the outdated practice of feminine hygiene, and the white men we recognize today as “douchebags.” They are both, it bears repeating, useless, sexist tools.It's a well-argued case for using "douchebag" to mean the blinkered, entitled fool who mansplains that his white male privilege ring should be kissed in every circumstance, while denying the ring exists.
That said, I'm not entirely comfortable with the article ... though I guess it may be my "liberal guilt" insisting that the proper authority for what the proper designation of this specific sort of asshole is should not be a white male professor?
