Whatever he uses to argue. The following facts are universally true:
Problems could lead to anxiety, depression, over-fantasizing, social isolation, compulsive sexual behavior
Ignorance leads to problems,
Ignorance is caused by lack of knowledge,
Most porn users don't have basic knowledge,
Addiction sets in and creates bondage.
And faith and God is a battle-tested solution. There many but this is really the most effective.
God is love, justice, and mercy. Your view might be foggy but it's there from Jesus to Abraham to Adam. I don't need to explain it to you but his words are just and true and honestly sometimes a reflection of human nature (imperfection).
This isn't an counter-argument but a way to give you another lens in this issue.
Viewing post in Why do so many people want NSFW games?
Hmm.
Basically you say, oblivious people are prone to overindulge and can fall from one compulsive behaviour like "porn addiction" to another, like being religious and preachy about it, replacing one devoted behaviour with another.
While replacing one obsession with another is a thing, I would not limit this to people with "lack of knowlege", but rather to the overindulging itself, and that's not something based on knowledge. What is based on knowlege is the ability to blindly follow doctrine, be it religious or political.
I tried to find if there is a correlation between intelligence/education and consumption of adult entertainment. Could not find something conclusive. There are hints that higher education broadens acceptance and people seek a variety of stimulus for their mind. I will even claim that the average intelligence/education of the group that plays adult video games is higher than the general average.
Anyway, to get back on topic, sexuality is just such a basic need, people would be interested in it, no matter their knowlege or lack of knowledge.
Excuse me. I don't think anyone here is trying to to tell you what to do. Just trying to have a reasonable discussion and hear some other viewpoints. If Joyce Meyer is your only basis for Christianity, just know that not everyone is the same and from what I know a lot of those TV preachers don't actually follow God. I'm not judging you, I'd just like to know where you're coming from here.
