Exactly why do you believe this to be wrong? Religion reasons I assume - "Thou shalt not photograph totty" etc.?
Let's see: How would you like it if you were discriminated against because of your gender?
Here's a thought: It's called sexism. Sexism is wrong. This is not an opinion, this is a bloody fact. You do
not go around sexualizing women and expect everything will be fine, because sooner or later, you'd find yourself completely alone as you'll have alienated the decent people.
This image completely sexualizes women. to believe that sexualizing women is wrong is sexism towards women.
And if you'd actually bothered to read, you'd see I'm not in this because of religious reasons. I'm an equalitist.
Edit:
In case you can't tell, I'm on the verge of becoming quite snappy, as when I get into fighting sexism that's what I'm like. I'm very passionate about equality, especially gender equality, and thus am used to arguing against the same arguments that's been presented here.
