You are incorrect.

If this were true then folks who looked at more porn would be more likely to be addicted.

The number one predictor of porn addiction is religious affiliation, not porn use.

What you are saying is simply not true.

The problem is their moral beliefs are not in sync with their thoughts and desires, which causes guilt etc.

Scientists have reached consensus that porn addiction is not a thing.

What needs to be treated instead of porn addiction is the moral beliefs of the individual which are not in agreement with their porn use, which can cause stress anxiety and real health issues.

But the issue is the persons moral beliefs, not the porn use.

The only thing wrong with porn is the moral judgement some associate with it.

Just because you think porn is immoral does not make it true.
