"Young women are encouraged to pursue hooking up because that is what empowered women are supposed to do. Those who abstain are seen as unfortunate casualties of a culture rampant with slut shaming and repressive gender norms."

Uh, that is absurd. https://www.theglobeandmail.com/opinion/article-feminism-in-the-bedroom-can-leave-women-unfulfilled/

Maybe this is the case in some funhouse mirror corner of the internet, but my goodness that's embarrassing to see put forward as a serious argument by anyone.

"If a woman is more interested in having committed relationships, that should be completely fine, too. She should not be made to feel as though she is uptight, unenlightened or a sexual prude."

Good news, that is indeed completely fine already.

Sexual freedom means precisely that -- the freedom to govern your own sexual behaviour and choices.

Feminism isn't pressuring young women to be promiscuous, but true, it's not interested in shaming those who choose casual sex over committed relationships.
