I think he's offended that one crazy person's actions have turned into a generalization about men (yes, "some men" qualifies it, but since you can't tell "some men" from all the other men, any action that's meant to affect these "some men" affects all men, hence nullifying the qualifier. Furthermore, your grandparent didn't even use the "some").
A much fairer (and still true) statement would be "some people do risky, strange, violent things as part of their drive for sex." If you want to further dissect the issue into the different kind of strange and violent things men do vs. other genders' behaviors, that's fine too, but by comparing Rodgers to "some men," the implication is made that his actions are endemic to men (they're not -- they're endemic to violent, crazy people).
Maybe a more cogent point is, crazy violent people find a ready culture of misogyny to hang their urges on. Again and again and again, its women that are the target. This can and should be changed. I hope one day soon its no more accepted to publish 'player handbooks' than it is to distribute KKK race hate messages.
I'm not focusing on his actions here. His actions were the result of pent up, dangerous, toxic emotions. The same emotions that are felt (albeit to a lesser degree) by most men.
Most men just channel that into something else, like entrepreneurship (ie Zuckerberg), or drugs/alcohol/video games.
