The OP might have been better placed in Feminism rather than Relationships if you're wanting to discuss theory, but no matter.
My theory is that boys/men are often socialised that anger is the only acceptable emotion, hence any other feelings, frustration, upset, often come out as an outward display of anger - anger is seen as "manly" and aggression is seen as normal. If you look at toys and programmes marketed at boys, it's all guns, fighting, superheroes defeating the bad guys, fast/aggressive driving, generally proving you're "more man" by using your superior strength or intellect to "win" and this idea that if you are defeated that not only makes you weak, it means you're less manly.
Conversely, girls and women are socialised not to show anger as it's seen as unladylike (however old-fashioned we may think the term) and tends to be written off as cattiness/bitchiness, it's more acceptable for women and girls to show other emotions (such as crying in public) than to be angry. So your feelings of frustration, anger, etc are more likely to come out as tears than an actual expression of your feelings. Again, if you look at products and TV shows marketed at girls they are all about passiveness, looking pretty, waiting for a man to come and rescue you, being best friends forever, caring for things (babies, smaller children, animals)
Added to this, much of society is set up to be misogynist, women are often presented/thought of as men's "property" in various subtle ways and/or objectified generally. Sex is thought of as something women hold the key to and men have to "get". So we fall back on the conditioning from society/our childhoods, men use their superior manly strength and intellect to get what they want (as this is the way they are taught to get things) and get aggressive when things don't go their way. Women find that they slip into the passive role, try to avoid confrontation and tap into their "naturally caring side" in order to try and "tame" the man into being a good husband, and all the pieces fit, you end up in an abuse situation.
Of course this is massively oversimplified and men and women aren't quite so one dimensional, but these patterns of socialisation are present in society and they do support an abusive model of relationships, which is why violence is gendered (even though it can happen the other way around) and also why it is so common.
If you are in a relationship with an angry man, you are in danger. That isn't oversimplified - it will be true sooner or later.
