Hold on. What do you mean by that?

This is clearly a horrible violation of people's integrity and privacy. It's not about "chicks" getting raped. Would you wait for a Nerds around me and see people getting bashed by goons just like that?

It's a serious threat to people's security if it makes it easier to stalk unsuspecting people. Maybe I just misunderstood you but wouldn't the threat of just a single incident facilitated by such an app be enough to reconsider the importance of privacy?
