This feeling is like being eaten by rats when they outnumber you a thousand to one, like in Lovecraft's "Rats In The Walls". First of all before even writing this post I want to state the fact H. P. Lovecraft didn't care about all White people, he only cared about Nordic and Anglo-Saxon people. Which I disavow, I think all white and not jewish people are, for lack of a better term, "important" and should survive. According to UrbanDictionary, "Dago" is an "ethnic slur for one from Italy, Spain, or Portugal". I've read some of Lovecraft stories multiple times before I had Internet access. Pickman Model is one of them. If you search the word "Dago" (South European) in the text, there's one match: "At a guess I’ll guarantee to lead you to thirty or forty alleys and networks of alleys north of Prince Street that aren’t suspected by ten living beings outside of the foreigners that swarm them. And what do those Dagoes know of their meaning? No, Thurber, these ancient places are dreaming gorgeously and overflowing with wonder and terror and escapes from the commonplace, and yet there’s not a living soul to understand or profit by them. Or rather, there’s only one living soul—for I haven’t been digging around in the past for nothing!" Note how in all his texts (if I'm not wrong) he calls everyone "foreigner" if they're not Nordic. "Foreigners that swarm them", he wrote. So, the feeling that you described, of being outnumbered by """"minorities"""" in your own country is not new, this story is published in 1926. "Shadow over Innsmouth" is of course about race-mixing. An American, Madison Grant published a book "The Passing Of The Great Race" in 1916. He only cared about Nordic people, which, again, I disavow. But, to quote Wikipedia *"The book was also the earliest emergence of the white genocide conspiracy theory as The Passing of the Great Race specfically focuses on an aforementioned supposed "race suicide" of Nordics by non-Nordics."* I think this quote is amazing but I would say, instead, that it's the earliest *recorded* "emergence" of this theory, people just had to feel this way in Canada and the Thirteen Colonies/ USA when they were outnumbered by Indians. But, obviously since it wasn't recorded I have no proof, I "know it but I can't prove it".
