The woman who wrote that article is a feminist. No doubt about that.
She has a blog, in which she poses as the voice of a gender/generation to insist that young women are "quite happy settling for a mediocre job" rather than competing with men; equates wanting to have children with happiness, and working with lack of fulfilment; and describes her #2 "life milestone all women in their twenties should aim for" as "buying yourself a really expensive pair of shoes". She writes copious lists of fashion trends, but none of feminist theorists.
Nevertheless, a man has stated with enormous self-belief that her feminism is beyond doubt, so I shall bow to his superior everything by concurring.
