I've seen far more of the world than you'd think. And if an aid worker in Appalachia decide that my country was a shithole based on what she saw I'd refer to her the same way as I do you.
If your denigration of other people, especially dark skinned poor ones makes you feel better it says far more about you than it does them.
You're nothing but a fucking bigoted c word as far as I'm concerned.
