Ok, let's have this conversation. I'm assuming you've actually read a decent portion of his writing, since you seem to support the claim that it reeks of misogyny, and that you're not just parroting back claims from a bunch of people trying to fit it to a narrative (who haven't read it themselves either) right? It's available here if you haven't: http://www.scribd.com/doc/2259...
So let's talk. The boy clearly shows signs of blatant narcissism. In the first couple pages he brags about having visited 4 countries by the time he was 3, as if any child that age could gain anything meaningful from that experience. He goes on to describe a facile and warped world view, including how much joy he took in excluding his arch rival (a boy) from his 6th birthday party, classifying being denied entry to a roller coaster ride at 7 because of his height as "an injustice", and overall demonstrates a clear love of power, money, and status in settings that have no bearing on gender whatsoever. Where's the misogyny there?
He talks at length about how he refused to get a "low class retail job" because he's "an intellectual who's destined for greatness." He decides he'll be a screenwriter for about 2 weeks until he realizes they don't make much money, and then bails on it. He takes a college class, but quits halfway through because he's physically disgusted by the site of a happy couple sitting together every day. He took a janitorial job out of desperation, then quite after 5 hours because it was so beneath him. Where's the misogyny there?
There's a lot of misogynistic expression as well, of course. At one point he tells his mother that she should "sacrifice her happiness to secure his future" by marrying a rich guy she only wants to date. And yes, there's a lot of ranting about how women ignore him. But if you actually read even a little bit of it, it becomes very clear that this is a fundamentally delusional person no matter what gender he's talking about.
If you actually look at what he says, it's clear that he feels entitled to EVERYTHING. Not just women, but money, power, respect, friendship, and luxury. He's clearly not able to connect well with other people, and he basically viewed women as a prop in the perfect life of adoration that he felt he was owed. Is that misogynistic? Certainly. But taken as a whole his delusion was no more misogynistic than it was hateful of the entire human race indiscriminate of gender. Hell, he even killed twice as many men as women.
So then why is it that the outcry over this tragedy has immediately become slanted towards "violence against women!! men are terrible!!" The kid had horrific attitudes toward literally everybody around him, and was clearly an entitled little shit in every aspect of his life. In his world view all women were sluts and all men were intellectual nitwits and brutes, and NONE of them deserved to live if they got in his way. He outright said as much. Yet the social reaction to this not only emphasizes the effect it has on women, it actively EXCLUDES people from talking about the effect it has on men, and implicitly tries to lump all men in as perpetrators of the distorted mindset that Elliot Rodger had toward the world. It's divisive and bigoted, and frankly it's fucking disgusting.
