That is a) not how the language works and b) an atheist would never try to convince anyone about anything religious. Aka: convert. Because that would mean for him Atheism is a religion, which it is not. I am an Atheist. My inner self is convinced: there are not gods. And that is it. I do not try to make you go away from your god. And I myself: have no god. There is no church or cult of Atheism. there is no organization (perhaps in weird countries there are, who knows?), there is no path to follow, there is no morning or evening or any other ritual, there are no prayers, there is most certainly no evangelism towards Atheism.
