Young women don’t find feminism very relevant. I ask my students all the time, and they tell me feminism has achieved all its goals and is no longer needed.
It’s true that feminism doesn’t have much to offer to young women. Until they try to have actual careers, give birth (without the mediation of their parents), make serious money, experience health problems, etc, there truly is nothing for them in feminism. The only thing anybody has come up with to offer as a substitute for feminism among this group is orifice policing, and that energizes only a small segment.
And that’s the real reason why young women don’t see the need for a candidate who will champion feminist issues.
