OE

xenophobic, bigoted The blank here is defined by the second half of the sentence. “Patriotism” represents the “elevation of one country to the rank of quintessential on Earth,” which implies that one country is the purest example among all countries on Earth. So your blank should be something that involves the “demonization of other people.” A good fill-in would be prejudiced. Minatory and truculent are not quite a pair (the former means “threatening,” while the latter means “aggressively defiant”), and unethical and nationalistic have no relationship to each other. It is certainly true that excessive patriotism is nationalistic, but this word does not match the proof in the sentence.
