Oikophobia is, in psychological terms, fear of one's own home. In political terms, however, it's the repudiation of your national and cultural heritage. The right wing accuses the left of it constantly, and its overdone, but the claim is not wholly without merit.
Indeed, without knowing the term, I've noted the irony of it frequently. The West, culturally, is the heir of, in chronological order, Greek thought, Roman thought and Christianity. While we're at it, we'd note that the European East, where not mixed with the West, is the heir of Greek thought and Christianity, with Rome omitted.
In terms of influence, however, the West is, in order, heir to Christianity, Roman thought, and then Greek thought. One of the features of Christianity is tolerance, due to love, of all humans. The irony of much of modern leftist thinking is that it's taken Christian views, including tolerance, the equality of women, and the like, and sort of perverted them. That's given rise in recent years to some strains of thought in Christian Nationalism and in Populism.
Anyhow, one of the things I've noted from time to time is this. In no other society but one heavily influenced by Christianity would questioning everything about what's inherent in the culture, including at least cultural Christianity, be tolerated. The broadening influence of Rome is part of that as well. That's why, ironically enough, oikophobia tends to be limited to European cultures, including our own.
I've also personally observed, but I don't think I've posted on it, that the explosion of academic sub disciplines in recent years creates entire fields that only exist in academia. I.e., while most of what a classic liberal education provides is useful in all sorts of ways, and employable in all sorts of ways, some of the more recent sub disciplines are wholly useless outside of academia. All the recent higher education focus on, for example, transgenderism that has schools, such as the University of Wyoming, employing people to worry about a demographic which is something like 1/2 of 1% of the American population, but which has morphed in record speed from a demographic that previously was subject to psychological pondering to one now where a 200 lbs+ man can claim to be a girl and then sit around in a sorority, crossed dressed, but with an erection.
What this notes is that, but for academic oikophobia really can only exist in that atmosphere:
The Paradox of Academic Oikophobia
What makes oikophobia paradoxical is that those who are most infected by this pathology are the greatest beneficiaries of national largesse. In other words, they bite the hand that feeds them, and they bite it the hardest.
