So who exactly is being harmed here? Who are you defending, and against what?
We're getting closer to the crux of the argument, here, which is a good thing. The "crime" in things like this, every time, is the display of a female fantasy figure for the purposes of appealing to (presumably male) sexual desire. This typically ignores is the lesbian and bisexual females who enjoy "eye candy" just as much, but that's a side issue. The fact is, men are being criminalized for enjoying and desiring the female form. And it's wrong.
That becomes especially clear when arguments get made like "this is just fodder for teen boys to masturbate to!". As if that alone makes it wrong. When called on this, typically the old slippery slope argument of "porn leads to sexual abuse!" gets trotted out, despite having been thoroughly debunked. This is especially glaring when the same people ignore violence in the same entertainment media they criticiase for sexual imagery.
The whole arc of the argument reminds me of the gay marriage battle, with psuedo-arguments that really don't hold up to examination covering the fact that people simply disapprove. They think it's immoral, but they try to paper over that with something more substantial and it fails. What it really comes down to is good old fashioned prudery.
