How Mobile Phones Kill People

So I was on my way home the other night, walking through a park. I was behind an unknown girl, we both came from the subway station and apparently had the same way home. Upon exiting the station, she had taken out her mobile phone and was now talking on it, while I followed her on the dark paths.
She didn't say much, just "Yes" and "uh" from time to time, and it gave me the impression that THERE WAS NO ONE ON THE LINE. That she only took out her phone and pretended to talk to someone to prevent me from raping her. But why would I do that? Yes, she was cute and seemed to have a great body, but it was approx. 20 °F, I'm sure as hell not raping anyone under this freezing conditions! Well, of course, I never rape anyone, but even if I would, I wouldn't. Not if it would be embarassing for me.
But maybe it was just to prevent me from talking to her? There are girls everywhere, constantly talking on their phones or texting or surfing the web and whatnot, or having their headphones plugged in. That creates an additional barrier, preventing men from approaching them, so I dare to say that a lot of romantic encounters are not taking place (including rape). That means, there are children unborn, just due to the fascination and overuse of mobile phones. Guys, this is worse than abortions! With an abortion, at least there was sex before, there was fun. I'm talking real fun here, not playing some stupid games on the phone.
This should stop, at least in the public. I can't help imagining someone travelling back in time. Medieval people see them, a string attached to their ear, suddenly starting to speak to some invisible person. They would sure as hell get burned as witches or locked away as crazy people. And I second that, we should introduce that again!
