Of all the possible complaints about this they could have really dug into, of all the things that are wrong with it, Jezebel has to make something up to be the core of the article?
W.T.F.
Oh wait it's Jezebel why am I expecting anything other than sensationalist clickbait that sets back the very cause it ?
So yeah, the whole thing is terrible in lots and lots of ways, but since there isn't actually any requirement she be naked, being naked in a bathtub isn't inherently sexualizing, especially in this circumstance. Nudity, if the artists do decide to go with nudity, is a common theme in depictions of suicide in fiction meant to carry emotional wait for legitimately good reasons (symbolic of vulnerability and the discarding the mask they wear to shield themselves from a harsh world etc. and so on), and there's a reason it's a common motiff for both male and female characters.
I'm not saying the competition isn't terrible (Meat bikini? Really?), that the winning strip isn't likely to be terrible (they don't require sexualized imagery but by current DC standards I've no doubt they'll jump for it), but personally I'm more raging that Jezebel consistently does this... hack job of reporting on terrible things, where they feel the need to add layers of bullshit on top of it and (often enough) end up being outright sexist themselves.
I'd like to rage at DC but honestly after all the stuff they've done recently I've exhausted that particular font.
Edit:
I've been spending a good bit of time upset with Doctorow on BoingBoing lately too for the same reason. It infuriates me when people are right about the ultimate point and then undermine themselves by building their argument out of bullshit instead of the obvious stuff right in front of them that is obviously wrong. Rrrrrrgh.
