Dragan,
Are you saying that humans are intrinsically moral? I disagree. From the casual cruelty seen in every schoolyard to celebration of wealth accumulation while some across town are in abject poverty, it does not seem that humans are naturally moral or good.
Most religions recognise this and advocate that we must strive to be moral. I can't see how any religion can be seen to claim a monopoly over morality if "belief" includes the idea that we are sinners and need to strive always to behave morally. That isn't a monopoly, it matches fairly well with the observed reality.
And you cannot deny that those who celebrate and value selfishness are more likely to claim pride in their atheism/agnosticism than in strong religious beliefs.

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
