So a "fundy atheist" is an atheist who is fundy about anything other than believing in God?

Not necessarily—again as I already said previously. For example, an atheist can be fundy about American-made muscle cars, which qualifies as something "other than believing in God" but does not qualify as an "atheistic view." At no time have I argued that atheists are fundy about just any old thing "other than believing in God." This circling about to already addressed points is rather curious and becoming tedious. I implore you, please, when drafting your response to consider whether or not you are raising something we already went over.

If the "fundy atheist" is fundy about things not related to their atheism in any way (as it obviously isn't, and as you accept) ...

The distinction I drew is—again—that they are fundy about their atheistic views, not atheism in and of itself. It certainly is not obvious to me (nor did I accept) that one's atheistic views can somehow be unrelated to atheism. Atheistic views are by definition related to atheism. However, "related to" does not mean "the same as" (i.e., metaphysical naturalism is an "atheistic view" but is not "atheism").
