No, the ultimate goal is awareness of others around you and not just yourself. No laws need to be added if people could take the time to realize how their actions affect others. You want this stuff to stop then next time ask yourself how does she feel about my behaviors, am I sending the message I want to send. If your tool for meeting women and engaging in sex is saying "hi" on the street, then you should listen, as these women are telling you they don't want that. Maybe start thinking "hey maybe I am going about this the wrong way".
I am for one against any law that would forbid anyone to say hi. I am one who is for informing others how their actions affect others.
