Is it really that surprising given how many fetishes there are? I mean some people like em old, why not young? Not to mention young is disirable in girls in most people to begin with (just not that young).
I think we should take note that all primate males, during puberty attempt to intercourse with just about ANY female, wether rape or consensual. I don't think pedophilia is even the point here, I think when it comes down to it, people are just sexual. Before the victorian ages girls in general, as long as its not too young (babies) or too old (hags) have been objects of sex, a picture with females or varying ages is just that.
It wouldn't surprise me if there were in fact a lot of pedos, i am pretty sure out of the people i know, a handful must be pedos but obviously aren't telling me. Of course you can't prove there IS because well, no one's gonna tell you they are. So if we've lived for this long and haven't really had a large problem with pedos.. why now?
Of course, the kind of thing tends to scare people (i don't know why), but as long as you're not taking advantage of some kid.. i think we can all relax.
