Kink is actually relatively tame as far as &quot;violent porn&quot; goes. Insex set the standard in hardcore S&#x2F;M during its day and was actually forced to close over scrutiny from its perceived obscenity. Many modern S&#x2F;M sites owe their style and aesthetic to Insex&#x27;s grisliness. Speaking of which, a documentary I&#x27;d recommend viewing on the topic is <i>Graphic Sexual Horror</i>. Be sure to watch it during the day.<p>Of course, I&#x27;m not counting things like guro, crushing or vore. S&#x2F;M is a long established subculture, though I suppose the more hardcore stuff is relatively recent in practice. I don&#x27;t think it should be marginalized in the slightest. It&#x27;s certainly <i>not</i> a joke, however.
