I hiked along some cliffs in Mull where there was a large feral goat population, and was swarmed by these fuckers (we call them deer keds). Absolute nightmare fuel. They would quickly shed their wings and nestle in hair (mostly my beard) or inside clothing. They're really flat and leathery, and cling on for dear life - making them unreasonably hard to remove (they would wriggle free from my fingertips as I tried to prise them off.) I removed several dozen over the day and still found their corpses in my laundry.
The only goats we saw were dead and stinking. On the plus side, the weather was bad enough to mostly keep the midges at bay. Without a doubt, the worst experience I've had in the Western Isles.
I would guess it was interpreted as the slur for Japanese people (perhaps an automod thing - never really used Reddit though so I dunno how these things work in practice.)
