"internal affairs like domestic terrorism are not the State Department's purview" That's irrelevant. I'm afraid you can't back the article with official state documents, only with fringe mentions of obscure scholars, and many sources included don't even do so, contrary to your claims. Cite a single state or nationwide US document that declares and effectively connects anti-abortion violence with terrorism (any kind of terrorism). Abortion is completely unrelated to terrorism, as there is no such thing as "anti-abortion terrorism". If I am missing something big here (I doubt that), then the title of the article should be changed accordingly to Anti-Abortion Terrorism; I don't think this is the case.
