I mean, whats your selling point?
So let me get this straight.
You want me to abandon the illusions that give my life purpose even though they make my life objectively better?
Are you sure you thought this premise through?
I think the reputation for nihilists being brooding, melancholic, fragile, phobic and obsessed with death is somewhat deserved. There is also a tendency to associate nihilism with people who are bi-polar or have wild mood swings with the occasional manic episode.
I always get the feeling that the narrator is somehow trying to paint the setting as better than the real world, but its actually far worse.
A nihilist trying to sell you on nihilism because it will somehow make my life better or make me happier should maybe take a look in the mirror. I know this is anecdotal, but most of the nihilists I've met are some of the most miserable people on earth. They either spend every waking moment in a state of existential despair or in pursuit of hedonistic debauchery in order to try and chase away the blues.
