First, on the subject of "women are crazy" vs. "men are assholes". During my single life, I had many conversations with my girlfriends about how guys are assholes. They just don't get things, don't respond to situations appropriately, lack emotional response.
As I started to hang out with my boyfriend and his friends, though, I started to hear more and more that girls are 'crazy'. I think this is the equivalent feeling among a lot of guys, similar to the consensus among women that men are assholes. This equivalence got me thinking.
To be a true feminist, and thus to expect fully equal treatment between men and women, one must do the hard work of examining your own biases towards the opposite sex. So if I disagree that women are crazy, then I have to figure out what is causing me to believe that men are assholes, generally, and how that relates to the feeling that women are crazy.
Here's what I came up with. Women and men have a differing tendency of reaction and action, the former being a purely internal process and the latter being a purely external process. (Of course all of these are sweeping generalities and say nothing of the specific). So, given a situation, women are more likely to react to it, where men are more likely to act on it. Thus, women spend more time considering, pondering, investigating the details and the emotional consequences of certain actions or observations they have made. Men on the other hand are less likely to consider how they are reacting to the situation and more likely to just do something about it, or ignore it (which is actually, in many cases, a quite forceful action). As such, women are perceived by men as 'crazy', since they are likely to make perceptions or observations about a situation that a man doesn't. And men are seen as 'assholes' because they act on the situation without taking into account these perceptions and observations that feel obvious to the women.
I think it's nice to frame these generalizations this way because I think thought of in this way both sides have work to do. And perhaps this is one of the great benefits of being in a relationship. For women could learn from men how to act on their feelings and men could learn from women how to put their feelings into action.
Of course the words men and women here are somewhat useless, as I think in any relationship, be it heterosexual, homosexual, etc, it's not necessarily the gender that determines who's more or less assertive, more or less emotional. This is just a way to frame the conversation of one kind of division you might find in a relationship, and how learning to respect the other's skill is the first step in learning how to incorporate that skill into yourself.
