Not true. Not true at all. Have you heard Bernie’s stump speech?
“Women deserve the whole damn dollah!”
Seriously though, the most pressing women’s issues, as I see them, are rooted in economic injustice. If you lift people out of poverty with policies like a $15 minimum wage, their ability to help themselves is massively facilitated. There are other issues, like discrimination, childcare, paid family leave etc all of which Bernie hammers on the stump, but the real taproot is poverty.
Hillary hammers those issues too, no doubt about that. Maybe you hear her and not Bernie due to a difference of emphasis. That’s probably as a result of the fact that Hillary’s got little intention of making changes to the economic aspects of the social contract.
Hammering on social wedge issues has been a standard way of deflecting attention away from economic issues for decades, especially from the Republican side. Not to say they’re not important, but I think the most pervasive form of modern oppression is definitely economic, because poverty undercuts your whole life and makes issues like racism, sexism and violence so much worse.
