Amazingly I can use those terms in reference to anyone from anywhere on the planet.

Yes, they are derogatory terms and used as a means of comparing someone to a person not achieving as much as others, but mockery is a key component to social cohesion.

I think her linking all of those terms to 'black people' (Or people she thinks the word 'nigger' is referring to) is the real product of a racist mindset here.

But I'm sure her gulag school has air con and you won't get raped while there, so there's that...
