The difference is, Ellis isn't using American Psycho as an example of how people should be behaving. Stoklasa actively uses stereotypes to justify his arguments, such as when he says that the only thing men (and thus Anakin) care about is "Is she hot?" and "getting off" when that's clearly not the case in the film and for most guys in general. Similarly, he uses stereotypes about women ("women want guys who are assertive" and "nervousness gets old fast") to describe why Padmé has no reason to like Anakin -- not to mention all the BS he brings up about cars, jobs, etc. Or when he says women "like to talk about themselves a lot and don't really care what you have to say." He actively uses stereotypes as arguments. And you might say it's just humor, but then he really has no argument at all, since almost everything he is critiquing Anakin and Padmé for is not falling into line with stereotypes. And even the humor isn't an excuse because his points aren't even funny. Ellis was satirizing the yuppie and 80s culture by showing that it promoted a culture so self-centered that people wouldn't even notice if a psychopath was among them. In no way was it endorsing chainsawing people, though. On the contrary, Stoklasa consistently uses stereotypes about men and women as evidence for why the romance in AOTC doesn't work. And he doesn't even have the decency to be funny while doing it -- it's just crass.
