Serious answer
I grew up in Cornwall. For every 1000 people, 977 are White. The school I went too had only one non white kid there. My grandparents were what I call ignorant racists, no malice or actual prejudice, but if they saw a black person whilst out shopping they would call their mates to tell them of this unusual occurrence. My best friend was a massive racist, he emigrated to Australia where he fits in just fine. A lot of the people round here are very working class and use racist terms without thinking, I usually put this down to the fact that no-one is around to be offended. Chinese people are referred to as chinks, anyone with light brown skin is a paki including the Turkish people that run the local kebab shop. Black people are either coons, nignogs or coloureds. My mother in law thinks that coloureds is a perfectly acceptable way to refer to black people, again, no malice or prejudice, just ignorance. HOWEVER, it is getting better there are 4 black people to every 977 white people in Cornwall but thats probably 4 times more than 20 years ago and ignorant racism is on the decline so I agree that upbringing and social conditioning can and do play a part. But my sister isn't a racist and she was bought up surrounded by racists, mind you, she believes in God.
