I think the problem that some men have with understanding subtle forms of sexism, is that they don't see it as damaging. I liken it to a water faucet that drips inconsistently, but for months...then years. A male CEO harassing his female administrative assistant for sex, or she can forget about that promotion is an example of what many men think of when it comes to misogyny, harassment and sexism. Many men would never act like that, and they believe that harassment usually comes only in that blatant form. But, there is a category that is subtle and harder to call out, because like the leaky faucet, it's not as obvious as a pipe bursting, and a room filling up quickly with water. Yet, it nags at you. You know you should fix that faucet, but you don't. You keep putting it off. Likewise when women deal with men who for some reason, feel the need to call them cutesy names to get their attention, or toss out the joke about women's intelligence to get a laugh, it's annoying. Women should tell these men to stop, but many don't. Who on earth likes a leaky faucet? Doubtful anyone. But, just because you don't rush to fix it doesn't mean you like it. And sadly, you may stop hearing the drip after a long time, and just learn to live with it. That is everyday sexism, from a woman's view.
