Now, that's just silly. Elliot Rodger, the shooter, was not a "shlubby arrested adolescent" with a Jewfro. He was, in fact, slim, half-Chinese and not bad looking, resembling the nerds of The Big Bang Theory much more than he did the shlub.
He also happened to be seriously effed up in the mental health/emotional stability department, the real reason behind his acting out in such a horrific manner.
