To be perfectly honest, to what end does one host porn? Are pictures of anatomy in neutral ways still porn? Are artistic renderings of the human form? Are typical childhood photos? Specifically, the best way to combat the moral outrage that is sexuality (and all subject matter therein) is to have a series of good discussions with [your] children. Truly, any interested child will find "pornography" regardless of having a relatively "safe" outlet such as the Commons even within the scope of normal life. Any child telling you they never played 'doctor' is a fucking liar.
I'm certainly not stating that children should be exposed (har har) to pornography repeatedly, only that anyone looking for it need only open their eyes. To frame pornography in a light that sheds educational value is truly the best way to supplant the horrors of sex from the would-be innocent kids out there.
The truth of the matter is that some people get off on pictures of feet. Are pictures of feet, thus, porn? To what end does the definition become a four letter word? It's all about context.
On another note, as a 'civilized' culture, [we] are migrating further and further towards the notion that sex is evil, dirty, and not to be discussed or viewed ever, just as the slippery slope will lead to other less desirable facets of moral outrage--and that's a goddamned shame. There is nothing wrong with sex; [we should] stop insinuating that there is [something wrong with sex] to everyone, whether they listen or not.
