"atheists are a mix of narcissism and nihilism...they either don't believe in anything or only believe in themselves"
Is there something wrong believing in yourself or do we always have to put faith into others or a god?
Self belief you can live a good life, do the right things and are justifiable for your action does not make you narcissistic.
And to not believe in a god does not mean you believe that there is no meaning to life or you believe in nothing. Do you need a god for there to be meaning to life?
