Very well said. I would only humbly add that maybe it should be a combination of the Greek "oikos" (household, e.g., "economy") and "hatred", ala "misanthropist" or some such.
The left always seems to be swooning over the latest gang of designer thugs. Right now university book stores are featuring dozens of earnest attempts to understand Islam. Back in the 1980s the lefty Sandalistas were flocking to Sandinista Nicaragua. In the 1970s the left was busy understanding the rage of well-born terrorists in the Weathermen, the Italian Red Brigades, and the Baader-Meinhof gang. A decade before that it was Castro and the execrable Che Guevara. All of those thugs would have got nowhere without the fawning of the luvvies on the left.
You might think that these dictator lovers are evil, and you might be right. But conservative philosopher Roger Scruton talks instead, in A Political Philosophy, of a kind of sickness: "oikophobia." It's a fancy Greek neologism for "educated derision at... national loyalty," always siding with "'them' against 'us,' and the felt need to denigrate the customs, cultures, and institutions that are demonstrably 'ours.'" In short, as Scruton writes, it is "the repudiation of inheritance and home."
