So basically the Parkland shooting was caused by porn? I just thought the ahole just hated everyone.
Your attempted mockery by oversimplification fails.
Widespread pornography and the acceptance thereof is both a symptom and a contributing cause of the ongoing coarsening, degradation, and dehumanization of our popular culture. Animalistic behavior, including casual resort to violence, are a predictable result of a degraded, dehumanized culture. Pornography, in isolation, did not cause that jerk to murder his classmates. Pornography, along with widely accepted: violent entertainment, vulgar and abusive entertainment, promiscuity, abortion, atheism, socialism, and other similar factors combine to form a culture which is a psychological toxic waste dump. One should hardly be surprised to find casual violence in such an environment.
I have a kind of theory about the "solidarity of goodness" and a corresponding "solidarity of evil." Every good thing strengthens and builds up all good things, and every evil thing is a factor of all bad things.
Sometimes the connections are a little obscure. However, I'm pretty sure that porn is in league with indulging extreme impulses, selfishness, contempt --- interior states related to murder --- and not on the side of gentleness, honor and truth.
When I was in high school in the mid/late 50’s they blamed Elvis Pressley and rock and roll in general for the decline and coarsening of civility.
