Sexism is not stereotypes or personal feelings or attitudes (although those can by misogynistic). The academic (and consistent) definition of sexism is a property of a society where one of the sexes has less power than the other, and the mechanism by which that imbalance of power is perpetuated.<p>Of course, sexism occurs <i>because</i> of internalized biases that are very hard counter unless people actually seek them out, and try to change <i>the ones that cause an imbalance of power</i>. Because those biases are internalized and widespread, it is very hard to find someone who isn&#x27;t sexist. Being sexist doesn&#x27;t imply blame, just like you couldn&#x27;t blame someone three hundred years ago for not washing their hands and spreading disease, because they didn&#x27;t know that diseases are caused by microbes. Just as observing disease-causing microbes requires study -- and in particular, distinguishing between disease-causing microbes and harmless or even helpful microbes -- so too does noticing sexism, and learning to distinguish it from harmless forms of non-uniform behavior towards others. But in both cases, the harm caused is real, and it is our duty to learn its mechanism and do our best to fight it.
