I've always found it equally insulting when men call other men pussies, as when women call men pussies. It's dumb, thoughtless and worst of all, harmful. Men aren't meant to be knights in shining armour or beacons of strength, and women aren't meant to be owned or weak or belittled. People should just grow up and allow people to be.
Tony Porter makes a well-thought out argument and appeals to men, but I could equally say it's for many women. Women who expect to be cared for, or marry rich men, or borrow power. Women can be misogynists too and hold patriarchy against men by questioning their masculinity.
