Nah, I don't think it's stupid. He's trying to frame everything in his "us vs. them" paradigm. To him, women's rights itself is a great springboard for his belief that atheism rules and religions drool; after all, mistreatment of women is intertwined with religious orthodoxy in some cases (which he draws attention to).
I actually don't think "idiot" really applies here (and I have no love for him); the guy is just insensitive AND bent on pushing his own agenda. Won't be the first, won't be the last.
Now, of course, these folks as in ("She was getting messages calling her a cunt, telling her she deserved to get raped, commentary generally about how feminists were ruining atheism.") get some IotD hellfire from me. "You were scared, possibly more than I think you should have been... THEREFORE YOU DESERVE RAPE" and "feminism ruins atheism!" just get "....... what" reactions from me, combined with contemplating how best to dunk these people in acid.
