Blatantly injurious anoreceptive violence—involving a combination of rapid thrusting, a girthy penis/object, and a prolonged duration—is rampant worldwide, facilitated by widespread ignorance (often willful), apathy, and misinformation. Considered along with the anorectum's fragility due to its anatomy and neuromuscular physiology [References: Anorectal Risks 1-3], it simply is not possible for resultant anal and rectal injuries and serious/chronic/permanent health consequences to be uncommon. When more than one person is involved such abuse must constitute severely criminal behavior, especially when considering additional factors such as a severely (self-)destructive mental disorder, a strong judgment-impairing drug, etc.
Pornography featuring at least anoreceptive abuse can have numerous effects on some viewers. Possibilities include serving as inspiration for their own activities, conditioning them to be aroused by suffering, and contributing to development of associated mental pathology: sexual sadism disorder, sexual masochism disorder, and perhaps even psychopathy at least for younger individuals.

People with those destructive inclinations currently are having a field day particularly with anorectal abuse and spreading disinformation. Some pornography companies are knowingly participating in and/or taking advantage of this situation. All of that is promoting societal decadence. This is happening because the vast majority of humanity never will place a high value upon the good health of at least someone else's anus; too many people do not wish to think seriously about anorectal anatomy, physiology, and health even though the anus is one of our most important body parts. Erotic anoreceptive activities therefore must be universally discouraged, and perpetrators of anorectal abuse against another person—at least and especially ones who inspire countless others—must face justice by any means necessary.
