When people are reading about Atheism, they should have the option to review a list of prominent persons who are atheists." 

 :::::I think that bears repeating for emphasis. While I obviously can't speak for everyone who might visit such a list, it is certainly why I first came to it. I'm not sure what else one might expect to find on a 'list of atheists'. By all means Nick, have a subcategory for 'self-defined atheists'. Have a whole new page if you like. Or retitle this one 'list of persons who are specifically identified as atheists', and strip out the extraneous entries. But a list of atheists should contain, well, atheists. Your methodology would have, I dunno, maybe Alan Turing, excluded from a gay and lesbian list for never having openly proclaimed his homosexuality. Nope. The thing to do, as with that example, is to see if they can be 'found guilty' of the offence.
