That blog post starts with identifying the Militant Fundamentalist Agnostic (bonus points for the accompanying comic from my favorite XKCD):
Religious literalists and creationists can be annoying, and liberal believers whose theology is entirely apophatic can also be annoying; however anyone who espouses atheism on the internet will soon encounter an even more annoying group: the Militant Fundamentalist Agnostics.
The what? Surely that’s a contradiction in terms?! Sadly not, the Militant Fundamentalist Agnostic, while pretending to complete ignorance of gods, will confidently assert the central dogma of the agnostic faith, and cling to it tenaciously. Their one dogma is the claim that atheists make dogmatic assertions about the non-existence of gods. And hence, by declaring themselves to be free of such unwarranted, beyond-the-evidence assertions, they feel themselves superior, not only to the believers, who have no proof of their deities, but also to the atheists, who have no proof to back up their supposed claims of certain non-existence.
