Okay, so there has been an explosion of hatred on tumblr right now in the wake of the shooting in California, some of which I think is reasonable, some of which I think is not. I'm not going to be arrogant enough to assume I'm the only sensible person on the planet, but I'll try to look at both points of view:

Gentlemen:
1. You may not know this, but women face a lot of harassment on the street or on public transportation. As a woman with ridiculously large breasts, I've gotten unsolicited comments and touches from guys I don't even know. I was eight years old the first time someone touched me on the train. Eight. If you think a woman may be irrationally defensive, it's because some of us have to deal with this crap on a daily basis. It can range from a guy yelling from across the street that he wants to jizz on her face to trying to rub his erection on her butt during rush hour. Sometimes it gets really scary with guys following them home. You may have the best of intentions, but recognize that the woman's protective instincts are up thanks to this behavior. You're afraid that you may be humiliated when she says no, but keep in mind she's worried that you may rape and kill her.
2. I know it's really difficult to approach a woman and ask her out, but if she says no, just fucking drop it. She's not interested. I know you went through all this anxiety and came out poorly, but she's not required to date you because of your trials. I'm assuming you're straight here, but if a guy comes up and asks for a date, do you have to do it? No, of course not. And if he threatens to kill you if you don't go through with it, how the hell would you feel? Also, if she turned you down kindly, please don’t react by calling her a cunt or being excessively aggressive. That’s why sometimes women give you a false number, seem interested but never call you, or whatever. It’s because they’re afraid of a reaction like that.
3. Dude, I don't care what she's wearing. That doesn't give an excuse. If your line of reasoning is correct — that if a woman dresses like a slut she's asking for it — then we may as well just cover our entire bodies like they do in some countries. Because I can definitely say I don't dress provocatively, just jeans and a T-shirt, usually a light jacket, literally all that's showing is my neck and face, and I still get this shit. So therefore I should hide my body even more? Cover up even my eyes because that's all that's left? Perhaps I should disfigure myself and become ugly so you don't feel attraction. No, that's fucking ridiculous to ask of me. Again, let's go back to the homosexual analogy: As a guy, if you're hot in the summer and take off your shirt and another man grabs your ass because your naked chest got him so bothered, I think you can agree that man is in the wrong. And before you mention breasts between men and women are different, I'll say this: If you honestly think a man's chest doesn't arouse sexual feelings in women (and gay men), you're a fucking idiot. Just look at every romance novel that ever existed and it's usually a shirtless guy. You shouldn't be prevented from removing your clothing as you like (within a reasonable degree) for that, just as women shouldn't.
4. Stop whining about the fucking Friend Zone. If she's treating in a decent albeit celibate way, then just appreciate that you have a good friend. If you just wanted to sleep with her and she hasn't shown interest, then move on. Because she's emotionally investing herself into the relationship and you're also stringing her along. Be up front and say your real intentions so she doesn't get the wrong idea. Then she can reject you outright and you can focus on another possible love interest. Because if you say Elliot Rodger serves as a warning to all women who friend zone, then that is fucking terrifying. You're saying a woman should sleep with any man who shows interest in her or else she deserves to get shot. I'd give another homosexual example, but they're getting old now.

Ladies:
1. I've seen people being upset at the defense "not all guys are like that." I know the difference between facing rejection and being killed is huge, but it is necessary to realize that most are not like Elliot Rodger. If you start lumping all men together into one mass, we can't start a conversation about what needs to be done to solve these issues. It alienates guys who are trying to understand. I'm not saying you have to excuse what some men do, but it's like having your parents shot by a black guy and then saying you hate black people. Yeah, there are lots of black people who are terrible and fit the stereotype, but you have to comprehend that many aren't. You're not going to attract support from them if you come out that prejudiced.
2. Okay, we have to admit sometimes women are assholes. I'm not saying the women who rejected Elliot Rodger were and I'm not saying even if they did they deserved to be shot. But women do sometimes take advantage of a guy's attraction. Not friend zoning, where you genuinely like the guy and want to hang out with him, only to find out he wants to date you. That's a different issue. I mean having the guy buy you things because you know he wants you sexually. You don't do that shit to friends. We can't pretend that all women are just innocently sitting around and misogynistic men are the problem. Guys can see how their attraction can genuinely be exploited and it causes resentment. We also have to frown upon such behavior. That's not acceptable.
3a. Guys can still give their input on women's issues. You can't just exclude them because they're not women. For example, I've never had cancer, but I'll give an opinion about the treatment of cancer patients. I may not be as informed of the problems involved, but that doesn't mean I have to be perpetually silent about it. Having a panel in congress on women's issues be all men is deplorable and needs to be remedied immediately, but again I'm not going to say only women can be on there too.
3b. Things like abortion aside, flirtation is a two-person process. If we want to talk about the rules, we can't be the only ones dictating here. We can't dismiss how courageous he was for approaching us in the first place. Yeah, there's a big difference between what he faces and what we face, but that doesn't eliminate his ordeal. What I'm trying to get at is, if a guy is courteous, don't mock him for his efforts or be a jerk. No, we're not required to sleep with him, we're not required to date him, we're not required to do anything. But when a guy complains that he did everything right and the woman acted like a bitch, then we shouldn't say he's making the issue about him. Let me give an example: I've seen a guy try to talk to a woman in a park, and she told him that she didn't want to see his ugly face. That's not cool. Like, there have to be locations where guys can try to flirt with us and if they're doing so in the way we ask, then we have to acknowledge that and return the politeness at least. If he starts becoming pushy about it, then yeah, we can fight back in the way we want. But if guys want to at least have the opportunity to try their luck, then I think that's not a crazy request. What else do we say, don't talk to women ever? There has to be some give and push in these interactions and to be respectful on both sides.

To sum up:
Guys: How the hell do you think inappropriately talking/touching a woman would work? You fucking know where the boundaries are, and don't try to justify in any context you're allowed to cross them. When she says no, she means it. It's not the end of the world. Try your luck again. She doesn't have to do anything for you.
Gals: We have to face a lot of bullshit everyday, but we also can't become the assholes that we're complaining about. No, we don't have to change ourselves to make guys feel better about themselves, but that doesn't mean we have to become prejudiced. We can't solve the problems by making generalizations, and we should also self-reflect to understand what men who aren't crazy like Elliot Rodger are encountering.
