The real problem is that many don't believe it's inherently wrong to exploit sexuality and sex of men, women and children.
They either don't take seriously or are overtly hostile to the notion that God has set in place rules that he expects his worshippers to follow. At least two of these pertain directly to porn in most cases:
Exo 20:14 "You shall not commit adultery.
Exo 20:17 "You shall not covet your neighbor's house; you shall not covet your neighbor's wife, nor his male servant, nor his female servant, nor his ox, nor his donkey, nor anything that is your neighbor's."
A large segment of those who call themselves Christian don't really believe this even though Jesus Christ himself states plainly that these commandments are valid and spiritual as well as physical in nature:
Mat_5:28 But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart.
Most don't believe it's a sin against God. Against Jesus Christ. They don't see it's something that needs to be repented of each and every time we engage in it.
They don't believe, think or recognize that it's bad for THEM. That it stops their spiritual growth. That it prevents them from knowing the Lord.
Exactly. See mine at #109.
It stops spiritual growth, ruins marriages and thus harms children due to ruined families, ruins both men and womens’ natural sexuality, and ruins children who are exposed to porn.
And when all those are ruin, culture is ruined.
It’s really quite simple and all follows immutable natural law.
