Nope, not anymore.
On the other hand, if all men suddenly disappeared, women would find themselves in a different world from the one they currently live in. One without truckers or farmers or ranchers or miners or plumbers or sanitation workers or garbage men or engineers. Considering that many women get freaked out by the sight of a roach, I think they’d get pretty unhappy pretty soon, once the lights went out, their toilets stopped working, and the stuff at the grocery store disappeared.
It’s true that women don’t need protection from predators anymore: men eliminated (or nearly eliminated) them long ago. But women still need men, and men still need women.
And by the way, the fact that someone’s a woman doesn’t make her harmless. It’s true that women are physically weaker than men, but obtaining a weapon easily overcomes that problem.
