I'll admit to being ignorant in at least some regards:
Where does this one come from???
You should not consider yourself ignorant for not knowing the term, because it is only used by a few people--I believe that it was coined by Jim Jatras. However, the degree of hatred and prejudice against Orthodox Christians in general shown by the professional Serbophobes and Russophobes in our governing elites, and their academic hangers-on, deserves to have a term for it. (For example,when they associate the very laudable tendency of the Greeks to support the Serbs with a defect in the Orthodox charcter that overlooks "Serb atrocities", or they claim that Orthodoxy caused the Russians to become communist .)
James George Jatras. Do a google search for his name to read his writings.
