Any advice that can prove porn wrong in all ways?

Do you mean is there one defining argument against porn that everyone will agree on?.. no not really, in the same way there isn't a defining argument against drugs, people still take drugs despite knowing the harm they cause. Denial is a big part of addiction and serves as a defense strategy to the addict in order to try and minimise or trivialise the problem. You can walk into a bar and start lecturing people on the dangers of alcohol or try fruitlessly to tell an alcoholic they have a problem and most if not all will not listen. There are no magic words, only stories and some stories might touch people more than others, people like a good story because you can structure an argument in a way people can understand and relate to
