I knew someone would bring this up, and even originally added that autoxenophobia is still xenophobia. But that distinction is irrelevant here. No doubt it is psychologically more complex, but for an internet forum that wants to avoid flamewars, it's just as bad—or arguably worse, since it sounds more legitimate and gives garden-variety xenophobia something to point to.
I'm not attached to the word, though; call it what you like. The point is you can't bash countries on HN. There was no factual content in the statements I objected to.
(And speaking of things someone is going to bring up, yes, my comments have made the flamewar worse and yes that is ironic.)
