Um, I was not born an atheist, like I was born a Korean Jew.
I became an atheist through my life's experiences/perceptions/analyses/observations , and yes, I am proud of my moral atheism, very proud.
If theists are as wrong and stupid as you believe them to be, then it's no feat to not be one. No moreso than it would be to not believe in sea monsters on the moon. Being proud of your morals is NOT the same thing as being proud of your atheism.
