I don’t need any authority to say something can or can’t be an addiction in order to recognise when someone has an unhealthy addiction to something (is unable to regulate their consumption of said thing to the point where it significantly negatively impacts their life).

Just like you can recognise that alcoholism can be a problem without being a complete prohibitionist nutjob, it’s possible to recognise porn addiction for what it is when you see it without being a puritanical nutjob. I don’t have any intention of shaming anyone for watching porn, I’m just pointing out that I’ve seen for myself that it’s possible to develop an unhealthy relationship to porn. As with any other addiction, there’s usually an underlying problem that has nothing to do with the subject of the addiction.
