Why when I say a black person ....
 

Why when I say a black person I feel like I am saying something racist?

cause youre a nancy?

I don't hate by skin color but I usually stereotype with it. I dislike you all equally. Even you, whitey.

Because your a racist! And if you don't stop being a racist and touching yourself at night, you won't get to enter the pearly gates!

because a black person is spoke of as a coloured person.

Because we are all the same color we just have different amounts of it.

The correct term for black people is "people with more melanin than Mexicans".

Because you are stupid!

because someone being black defines nothing about them and defining someone as a 'black' or 'white' person is racisty (almost racist)

when i talk about my friends id either say nationality, or by their occupation which defines a lot more about someone than their race

Why feel the need to mention colour unless it's integral to the conversation? Like moeloubani said, just use nationality.
