There is such thing as intrusive thought.
It would suck for anyone if this was enforced and suddenly had an intrusive thought about a child and got immediately arrested for it
I never said you should be arrested for thinking something. But if you openly tell someone you'd had thoughts of raping, molesting or cheating on someone, that's gonna set off alarm bells in anyone's head and be cause for concern.
That aside, you're now moving away from thoughts and onto actions.
Thinking about sexy kids isn't the same as telling someone you think that a kid is sexy. Or Tweeting it, although the fact that's in Spain where the age of consent is 14 again points to the fact that laws shouldn't be the benchmark for what's okay and what isn't.
That said if you tell another consenting adult and you act out your schoolgirl/rape fetish (and there's costumes and equipment on sale for that sort of thing) with them in the privacy of the home, that's still quite some distance from what should be concerning to - or any business of - other people.
In response to all of the above and in general...
It seems as though, culturally, some have turned a corner thinking that human beings are just out of control. They've switched off any notion of people having self-restraint, judgment, and personal responsibility in favor of a society where the government is supposed to think for you.
I can take enjoyment in thoughts that I have no intention of acting on. As an example, if I conceive of a hilarious prank on someone, I might giggle about that for hours, and even share it with others, and never even consider executing it because I know that it would cause more harm than good to the prankee. That's an innocent example, but it's indicative of entertaining enjoyable thoughts that you choose not to act on. I may enjoy the thought of eating a large dessert or a basket of french fries and choose to forgo acting on that because I'm not a slave to my biological impulses. That's why, by in large, many people are able to avoid becoming rapists, despite finding other people attractive, and even indulging in fantasies about being with those people. Beyond just avoiding rape, many people manage to be monogamous.
I'm a little disturbed by the number of people who do not seem to realize this. Pornographic materials for example offer a fantastic opportunity that so many people don't seem to appreciate. You do not need to actually
try everything you see in porn. I know, this is a wild concept. But it is possible to enjoy watching people do things that you have absolutely zero interest in taking part in. To some people, that may seem impossible. To others, it may seem painfully obvious. To demonstrate to the latter group, consider the angry significant other that discovers that you have viewed pornographic materials and is jealous. This misunderstands what the brain is capable of. To the former group, consider an action movie in which the hero shoots a bunch of bad people. Did you enjoy that? Did you actually want to go shoot people?
Violent video games, movies, artwork, and fantasies are not things that human beings will necessarily act on. We are capable of self-control and rational thought. Pornographic materials can offer a way to view something intriguing (and sometimes even physically impossible in the case of pornographic artwork) without actually requiring that the person desire to participate. I've never shot a single person, and have no interest in doing so, but I've killed a lot of people, sometimes in graphic ways, in video games and enjoyed it. And I've many times watched explicit materials and thought to myself "that does not look like fun", and kept watching. These kinds of fantasies or indulgences can be (not necessarily always) a release that actually reduces the urge to act on those fantasies. And it's for that reason that I think particular pornographic artwork has a place for pedophiles - anything that doesn't hurt people and helps prevent a pedophile from harming children is a good thing.
TL;DR - we are not slaves to our biology.
Edit: You know I had never considered this before, but this impression that adults must try everything they think of might result from assuming that adults behave and think like children.
Edit 2: I think it's far more valuable to view people as responsible individuals than biological automatons, even for dangerous and scary propositions like mass-murder and pedophilia. If we pretend that a violent videogame, or elicit artwork or rendering might cause someone to go act out some horrific violence on the people around them, to an extent, we excuse that behavior. They couldn't help it, they were exposed to suggestive material. The reality is that this is
not an excuse. To the extent that we hold these kinds of stimulus
responsible for the behavior, we remove that responsibility from the person who actually committed the act. And that's wrong to do.
