It has to do with the atheism community on Reddit. Even if, for sake of argument, the atheism community on Reddit is composed mostly of Vatican-sponsored trolls... it would still be a problem for atheists, because it would be giving atheists and atheism a bad name. Which, it is. It's the dominant atheism community on Reddit. How can continued misogynist behaviour there not be a problem for atheists?
