CBF looking at all the responses, but basically I assume the Muslims on the board are trying to say that nudity provokes unwanted attention and that naked kids are like free for all for paedophiles.
So some paedophiles look at naked kids, or even dressed kids in the street. They go home and whack off over it. They're sick, yes, but they've neither harmed nor denigrated the kid by doing this in private. I can't stop a paedophile from being attracted to kids, they're going to be regardless of whether the kid is dressed or not.
The point we're making is that nudity, and the human form has nothing that is offensive. Why is a penis and a vagina and breasts offensive? Furthermore, why can men go shirtless but women can not?
It comes down to your attitude towards sex, your attitude and shame towards the organs that provide life and a sense that being nude is basically allowing or inviting you to be raped/ogled/etc.
You guys can make as many paedophilia scenarios as you like, they're still wrong.
