4 of the 6 explicit criteria given are not inherently sexual in nature, and only 2 of those 4 are in any way related to violence (but even harassing is not necessarily violent, so it may be 1). Like I said, the only case law that exists relates to pornographic material as it is the most unpopular. That wording was ripped from other anti-obscenity laws that have had a hard time in court but have not yet been entirely struck down.
