A post at the excellent blog Man Boobz outlines such a scenario here. In it, David Futrelle, does an excellent job of explaining how the original poster (someone who goes by 'Scarecrow') is anything but a nice guy. He is in fact a festering pile of hate and resentment. This is a standard response to the 'nice guy' complaining about the hot chick dating the 'jerk'. You don't have to peel back very many layers to often reveal the alleged nice guy as an entirely self centered individual, who lacks basic respect for other human beings, especially women.
However, Scarecrow's story reveals another simple response to the nice guy complaint, and even a potential answer to the question Scarecrow himself poses to the world he views as so cruel and unfair. From his original post:
When I went to the pre-trial, I saw two young men (say late teens or early twenties). One of them had a swastika on his left shoulder. The other had arms covered with various tattoos. They were both skin-heads - real winners (sarcasm). They were obviously into drugs (I KNOW that the "we stole this car" was merely a rouse for them to deny possession of drugs and illegal firearms).
The thing that pissed me off:
They had their girlfriends with them: Two super-mega-hot women, a brunette and a blond. Both were busty, thin, and extraordinarily pretty in the face. They had no tattoos or piercings. They both looked quite ordinary, except for their well-above-average aesthetic appearance.
I wondered: Why do such losers get totally hot women, and men who are better off and "square" do not get the time of day from such women?
Read it in it's entirety here, if you dare.
So I'm going to propose one possible answer for him: because they are jerks. You see, when men view women only as object, and not real people, they completely fail to prescribe any personality to individual women. A females social worth is based upon her physical appearance, as all woman have the same basic programming, in the mind of the 'nice guy' misogynist.
Astoundingly it never occurs to the poster that these women, who were dating Nazi, Skinhead, drug users, might themselves be Nazis, or drug users.
Of course, not all women who date bad guys are themselves bad. But it astounds me that the poster doesn't even begin to consider this possibility. At the exact same moment he is criticizing these women for being with their terrible boyfriend, the poster is desiring to be with these women. Women who likely meet the same criteria that cause the poster to describe a man as a 'loser,' not deserving of hotness.
When I see a really hot girl with a guy I know to be a bad person, my first thought is not that she should be dating me. Honestly, my first thought is to question her character. If I know the guy is selfish, dismissive and rude, then I'm going to think that maybe she has some of these characteristics as well, at least in large enough amounts to not care if they exist in a mate. If I see a hot girl who is dating a nazi meth user, my first thought is not "dang, she should be dating *me.*" I don't want to date a nazi meth user, and the odds that she is one just went up by a lot.
I think there's some projecting going on here. The poster obviously would happily date these girls he saw in court, in order to have sex with someone he thinks is hot. He apparently wouldn't need to undergo much investigation into her personality, drug use or potential hatred of racial minorities. Obviously, rather than deal with this character flaw, he has projected onto all women and assumed they are just as shallow as he is. This makes him burn with the anger and judgment that only extreme self delusion can allow.
