One axe to grind with atheism I have is that without some notion of God the whole idea of equality is gone.
I'm sure atheists such as yourself think men and women are equal, and that black and white people are equal etc... But the secular humanist arguement for 'everyone being equal' has no foundation. Humanism traditionally has be a 'champion of equality' against the 'oppressive and bigoted Christian church'. Christianity has be charged with being homophobic, racist, classist and sexist. However it was Christianity which first came up with the notion of equality in the first place. Not only did they believe this doctrine but they promoted it in a climate where such as idea was unfashionable. In ancient Rome slaves and some foreigners were treated like animals who had no souls. Women were second class citizens. And anyone who threatened the Roman class system would be in severe trouble.
And yet Christianity spread embracing people of all colours, nations, backgrounds, genders and classes.
