I like the whole "walking home if they feel unsafe" thing. It's a pretty fucking dangerous world. And having someone there is always nice, even if it's not a guy. My boy friend always waits for my ride to come or walks me home.
A culture of consent is imperative to making public space safe enough for women and men to socially engage with each other in a healthy, fair, equal, and fun way for everybody. Don't want people feeling "paranoid" or "playing the blame game"? Well, don't be part of the problem! STAND UP FOR CONSENT. Don't body shame. Don't coerce. Don't victim blame. EVER.
