Having any trait that could be summed as, "good," be it appearance, finances, or personality, is going to be a boon. I don't think there's anything wrong with being concerned about that in a partner in of itself. The problem stems from their belief that the only factor that matters is appearance, which is quite convenient for them, if you think about it. One can make themselves wealthy or financially successful through actions they have control over, one can alter their personality to some degree, or at least the way it's shown to others. Appearance? Not really, at least not the way they obsess over it. Note that the likes of Sluthate or Lookism obsess over things like the maxilla, or a bunch of other irrelevant physical features that are hard to modify in anyway, as opposed to actually relevant things such as showering frequently or maybe cleaning up their appearance.
The fact these are things that are close to, if not outright impossible to alter, gives them a convenient excuse to not have to work to improve themselves, allowing them to whine about 'sluts' to their hearts content. They can act like nothing is their fault whatsoever, and place blame on the women alone for rejecting them--they obsess over appearance the way they do because it's the only excuse that couldn't be countered with, "well, why don't you go and work on x or y then instead of ranting about women all day?" And it's because of this single minded focus on appearance as being key to literally everything in relationships as a means of absolving them of blame in their failures, that causes the likes of Norwood, who can't grasp why someone would be with a woman who was the victim of an acid attack, or otherwise appear 'ugly' to them. It's really just a side effect of their obsessing over appearance as a means of, as they would put it: "Coping."
