Is it hypocritical for self-described feminist/egalitarian women to expect men to pay on dates? Why or why not?

For me, the answer is "yes" unless her brand of "feminism" is very libertarian/moderate and is only concerned with equality under the law and equal treatment in education/employment. But that seems to be universally accepted now in the west, among both the mainstream left and right.

So chances are if a woman describes herself as a "feminist" that means she is critical of perceived discrimination against and gendered expectations of women in the personal/social sphere.

Well, expecting men to pay on dates, or even just the first date, is a textbook gendered expectation. So arguably, if a woman claims to be a feminist but supports/defends aspects traditional gender roles when they benefit women(such as this), the sincerity of her beliefs should be called into doubt.

And IME this accurately describes most women, even young women, who expect or desire displays of "benevolent sexism" from their male partners, such as paying for dates, holding open doors, buying her flowers, etc, without reciprocation on her part.
