At one point in his latest copefest, Nick questions why people care about the conduct of others, and I feel this really strikes at the heart of why people like him are degenerate, social poison.
He fundamentally doesn't seem to understand that 'care' is the true currency of a functioning society; even money requires care to hold value. If no one cares, no one associates, no one does business, no one tries to find common ground and the whole social enterprise collapses. He's right that no one has to care about him, and truly this group is becoming smaller and smaller, but that doesn't make care a pointless, shallow endeavour. For well-functioning people, caring about coomer alcoholics is actually a great idea, if only so that we may identify and avoid them in real life. And it is obviously good to encourage people not to drink so that we aren't subject to their self-destruction and they aren't needlessly burdening our economy. Care is the act of someone who is internally alive and wants to see change in the world, and it's no wonder the idea is so foreign to him.
