If all the men were killed off tomorrow, what would you do?

I'd walk my dog at night! Braless!
Ok now your other female neighbors are doing the same thing. Her dog attacks and kills your dog. Then attacks you.

Well I'm calling the police!
Police no longer exist because there's no men.

I'm at least calling an ambulance.
Plenty of women do work as paramedics, so they take you to the hospital. However without men there's no surgeons so you'll bleed out or never walk again.

(Women start shooting other women walking around the neighborhood with dogs, and building 12 foot high walls around their houses to keep animals and other women out).

This is what you get in a world without men guys.
