"And what’s worse than that is that this sexualization of superheroines doesn’t seem to revolve around them as some sort of goddesses to be worshipped (though that would also be annoying) but as obstacles to be brought down." (Quote from a column by Ami Angelwings)
Weeeellll, maybe it isn't a trend that is heavily reflected in mainstream comics, but there are sites that sexualize superheroines in "dominating goddess" fashion. Although, you could say that, for example, Wonder Woman or Supergirl are by nature super-powerful women who could dominate most normal mortal men, so they already tilt towards the goddess nature by default. If "captured helpless superheroine" scenes in mainstream comics are reflected by more extreme sexual fetish sites, so perhaps are the super-goddess sites reflections of the heroines' natural states.
Ami does point out Phantom Lady's death scene in Infinite Crisis as an example of a superheroine becoming less-clothed in a moment of defeat, but I'd like to point out that Phantom Lady (or at least that particular incarnation) didn't have much covering to begin with. Her costume was a glorified v-type swimsuit, open in the middle, and it wasn't the fatal blow that opened it up any. The costume does appear tattered a bit, but really, she had about as much skin exposed normally.
Aside from all that: Doesn't this read like what I was saying a few posts back, about how people are worried about what other people are thinking? The whole ominous "I don't know what these people are thinking, but I'm worried it's not at all good" tone?
