Eh, this has basically been covered in previous social justice warrior columns. It doesn't hurt anyone to have a variant cover like that. You don't have to not buy the book to avoid it, you simply buy one of the alternate covers. I find complaints about this kind of thing to be ridiculous. I don't know what the fascination with this kind of thing is for people like the social justice warriors of the world. There are actual naked people on the covers of magazines that exist to objectify women, but lets complain about comicbook covers.
While I don't have any strong feelings either way for the review of that Teen Titans cover done by Janelle Asselin, I do question her choice of complaints. That cover is tame compared to just about every single issue of comics like Witchblade (or any image comic with females from it's inception). I don't find her idea about what does and does not make for good art compelling in reference to the what she is actually criticizing. Also, she noticeably speaks for every woman when she says no one with large breast would ever where what I'm assuming is meant to be a "strapless" top. Only, that is not the truth. I see large breasted women wearing strapless tops pretty regularly (weather permitting of course). It all depends on the style of the time more so than the want or need to see breasts. I routinely see this without any kind of breast support as well. I don't think they look like they are about to burst out either. If anything, the artistic reference was probably someone wearing a sports bra, which is what that looks like.
This is my one complaint about comics being mainstream. No one who actually reads comics really cares about the cover. It's there basically to let you know what you are picking up at a glance. I've seen few covers really show off anything about the contents of the issue, so it feels like an invented complaint when it's brought to bare against he Teen Titans cover.
I have just about had it with the Red Herring that is some jackasses actually threatened her with rape. It's terrible that it happened, but that doesn't actually have anything to do with her review, more about a few individuals fear of what they think she is capable of (ie. destroying their precious comic industry). No one is going to sit here and defend that attitude or justify it happening. But it's not really the issue we are talking about here and all it does is emotionally push you towards the conclusion of the author without offering you any empirical data.
You don't have to sit there and stare at it. Most covers are not eye catching (which is what I would say about that Spider Woman comic). That horrendous Catwoman cover is hard on the eyes, no matter how much T&A may be present. I quite like the Teen Titans cover because the work itself is extremely solid, though it makes it feel like perhaps the team may revolve around Wonder Girl in that issue(didn't read that, perhaps she is extremely central to that issue). That is reinforced by that strap that comes from her and encircles the whole team.
I do notice, as an artist myself, that a great many comic artists have just about everyone in skin tight outfits. This is an artistic shortcut. You know your anatomy, and that is just about enough to be a proficient character artist for comics. I mean, comics are the hardest commercial artistic endeavor to enter into these days, so that is no small feat. You don't see too many artists that add sufficient texture to their work for it to be really good (there is lots of texture on the Teen Titans cover). The Spider Woman cover is less so.
But, I do recognize that this column exists to point out things like this, so I do always appreciate that. If anything, as I have stated before, it makes me think about how I feel when I approach things. I have tried seeing it from the perspective that the author seems to take (ie. things like this are little more the sexploitation of women to attract men). Girls in comics are intentionally sexy, as are the men. Few people walking the earth fit the ideals laid down by comic figures, regardless of the sex involved. Comics are full of ideals. The heroes are powerful who use their abilities for good. Part of the ideal is huge chests and arms on men, powerful women of varying chest size who are as good as any man (if not better in many cases) and have petite little wastes and are too busy fighting evil to worry about what anyone actually thinks of them.
