When something becomes obsessive it's then an addiction and even more so when it prioritizes other things one should be doing and /or it starts to affect others around you and that includes abusing others online. There's two kinds of addiction....physical and mental and often the two play together hand in hand. The mental addiction or habit for another term is often harder to resist than the physical. A drug can either be a physical substance or a mental substance. What it all boils down to at the end of the day is a form of mental illness. Not being able to compartmentalise and separate things into an order to achieve an end goal that is beneficial and positive rather than negative and destructive due to the chemical formula in our brain.
So are you implying that Scottish nationalism is a mental condition? 😂
