If, hypothetically, I were an atheist, my atheism would be incidental and not the basis of my identity. Atheism is rejection of something, you can't build an identity on that.
Therefore, I would have to make my identity based on my race or ethnicity. What else would I have for the basis of my identity except something as superficial as race or ethnicity to contrast myself from other people? No wander ideologies like racism, ethnic nationalism, communism, and other harmful isms are the so appealing to atheists and non-religious people.
