These are the things most women know, this is why it's hard to reject unwanted advances, this is why we don't appreciate being told "Just fight back". Men and women are coming from different perspectives for these kind of encounters. Rejecting a woman is easy for men (Shut up), rejecting a man, especially one who might be sexist and certainly has power over you is a difficult proposition for a woman. It sucks, but that's what it is.
edit:
I would say from personal experience 8 or 9 out of 10 see politeness as politeness it's the last one or two that cause the problem. And trust me, being put in a situation where someone is quite obviously imagining you naked and thinking about...doing nasty things to you is one in which you don't want to be ever again. Makes you rethink being thought of as a frigid bitch.
I'll actually throw a little curveball to one part of that - I don't think it is any easier for the average guy to reject a woman than it is for an average woman to reject a guy. Just like a woman is worried about guy being a sexist aggressive douchewaffle (the 1 out of 10 rule), a guy is worried that a woman can go crazy psycho stalker on him. I think both genders have been equally burned just enough by crazy people that they let it be a large factor in how they handle the situation. The problem is that the consequences are severe enough that the relative rarity of it gets overshadowed (the average value of something is the percentage it happens * the magnitude of the effect). Seeing as both of the worst case scenarios could potentially ruin lives, it has a chilling effect on how we make our decisions.
I think our confirmation bias kicks in enough so that we see that it is "easier" for the other gender and "harder" for us (Hell, you could probably apply this to a variety of situations, not just this one). Women see men who just shoot them down aggressively and sort of wish they could do that, men see women who don't have to put themselves out their first for these things and wish they could be them.
I would be super curious as to modern studies done on rejection w/ respect to gender, though. This is just anecdotal from the people I've interacted with - I live in an area where women (should) have significant dating advantages due to supply & demand (there are a crapton more single men than single women in the area), so I readily admit that this colors my perspective. (Thankfully, I don't have to worry about the dating out here part currently)
Note: Not saying that the worst case scenarios are remotely equal, but they are both sufficiently shitty enough that it affects how we respond more or less equally; both sides are scared enough to be very, very careful.
Now, in the case of the indiestatik bit, the fact that one person was a developer and the other a journalist adds a power aspect to it that makes it much harder for the developer to reject the journalist's advances - my example assumes no power imbalance due to work / outside influences. In the developer's case, she's (unfortunately) more or less stuck having to be nice in her eyes. Even if statistically, the journalist is just clueless and wouldn't hold a rejection against the dev, the dev has to weigh the probability of the journalist holding it against the dev (statistically speaking: probably low) versus the potential effect if the journalist did (developer could hurt her livelihood).
I'd argue Jaffe's flaw in his argument isn't that of his gender or his race, but instead the fact that he's his own boss, and that he's someone who is not afraid of confrontation. The idea that someone can't just be like "dude, chill the eff out" or flat out be aggressive back to him, even at a power disadvantage, is something he's not used to / doesn't make sense to him.
In a weird way,
if that is the case, it might actually make him a really good boss.
