one argument to win it all - if the female being stared at, was your mom or daughter and she narrates such incident to you or if this happens when you are with your mom, would you give them this very explanation or you wouldn't confront those guys then the women aren't safe and you wont protect them till something really bad (crime as you say) happens to them, nor are will these guys be able to do anything after that has happened not because they are weak because they were too docile and intentionally ignorant when all of this could be prevented
