We understand the mechanism between guns and shootings. Point of fact we can't have shootings without guns.
Ergo we can't have shootings (in the context I've introduced shootings) without gun laws that facilitate them. See the
start/finish (root cause/end effect) relationship?
No such mechanism is in place for virtual porn and child molestation. No such relationship exists between the two.
See the
potential start/finish (root cause/end effect) relationship now?
"Could be"? Child molestations "could be" partly related to the number of ice cream parlors in society. It "could be".
Strawman.
We could speculate about an infinite number of things. To do so isn't good social science. Hell, it isn't even science at all. It's just a guessing game and "could be" isn't a get out of jail free card. You still have to do your homework and you still have to provide the evidence.
"Guessing game"! Many people are motivated to observe many laws not because they see the sense in and reason for those laws, but simply because of the thought of the
legal consequences if caught. Take motoring, for example. If speeding or alcohol restrictions were abolished tomorrow many people would undoubtedly drive faster than the current restrictions allow, and/or under the influence. One only needs to look at jurisdictions where speed and alcohol restrictions apply but are hardly enforced to see that. So, what do we tend to see from the more responsible Governments? Positive promotion of the
illegality of certain actions.
Now, this principle applies to virtually every law, to varying degrees, which means that there are many people who refrain from molesting children
simply because of the legal consequences should they be caught - no other reason. So, if a society freely permits the production, distribution and possession of child porn (which, for clarity, I'm defining as "sexually explicit images of children intended to sexually arouse" (which we can extend to just virtual child porn, if we wish, simply by adding the word "virtual" - the rationale and argument here equally applies)) what message does that send out to potential child molesters? At best: portrayal of child sexuality and Government's endorsement thereof is OK ; at worst: it's OK to sexually abuse children. In other words the
exact opposite of promoting the illegality of child abuse. How should one then reasonably expect many of those
self-restrained child molesters to behave? Should one reasonably expect that they will apply the same self-restraint when society is now telling them: Hey, exploiting children for sexual purposes isn't so bad afterall!
And don't forget this: Why do people, generally, watch or read porn - any type of porn? They watch or read it because of what porn is designed to do - sexually arouse. And what do most people do who have actively sought and achieved sexual arousal? They then seek relief. And how does one relieve oneself? Either with a "partner" (if available) or otherwise alone. And which of those two options would most people naturally prefer? And isn't it the case that many people sometimes allow their objectivity and judgement to be influenced when sexually aroused (ask Bill Clinton, if you're not sure).
And think about this: In a situation where there is a
reasonably perceived risk (ice cream parlors?!

) that something permitted by law for the benefit of a particular segment of society (probably a very small minority) could put many children at risk of molestation, does it not make sense to deprive that segment of what they would, admittedly, argue is a "right" in order to mitigate or eliminate that
reasonably perceived risk? Is a cost-benefit analysis not the right approach, even if a relationship
hasn't been identified between child porn and consequential child molestation (provided, of course, that definitive studies haven't been undertaken)? Again, does it not make sense to give children the benefit of any
reasonable doubt until such time as that doubt can be eliminated one way or the other?
