I've been an atheist / freethinker my whole life! As I like to point out, we are ALL BORN atheists! Since I'm also humanistic and a freethinker, I often use the term AFAH (which covers all of those plus agnostic), but not so much to self-describe but rather in writing for economy of speech.
Even more importantly, I hope someday that "AFAH", or similar initialism / acronym, can help non-religion-subscribers attain status, equality and power on par with what LGBTQ people have. Just think what the initialism "LGBTQ" has done, both for the subgroups represented by it, and as a "unifier". It furthers social identity and political recognition, it's affirmative and unifying.
