Have you read 1984? I'm not really following the 1984 reference.
Racism is about a belief in racial superiority or inferiority. So I guess it depends why the hypothetical serial killer hates white people.
Does he believe his race is superior to the white race and that's why he's killing white people, like a one man genocide? Then yes.
Most servers are there temporarily as they look for a high paying salary job, either directly or by getting an education.
And in most cases, you need to be in the city to apply for those jobs, to make the social connections that can help you find jobs, or to be where the good schools are.
Once you leave the city to go get a medium-paying job in a low cost of living area it makes it that much harder to eventually find the career a person wants.
Sure it's a decent life, small town livin', if that's what you're into, but people shouldn't be forced into that lifestyle because it's impossible to live in a city on an entry level wage.
