I don't see how you arrive at the statistic of "one in five american women experiencing a rape" from 28 rapes per hundred thousand people. Even if we considered that only women were victim of rapes and that half of the incidents weren't reported, it would still amount to something like 112 rapes/100k so around 0.1%.

Anecdotically, none of my female friends were ever raped which doesn't match with your assertion that "one in five American women experiences a rape".

I do think that our culture tends to objectifying women in the medias but I don't think that rape and sexual assault is as prevalent as many people think it is... There's also a lot of paranoia due to the media looking for good sensational stories and latching on any sexual assault story they can find.
