According to
Oxford (tell me if OUP is cucked or not; I mainly use it 'cause I'm a biased brit):
>I. the unfair treatment of people who belong to a different race; violent behaviour towards them
>II. the belief that there are different races of people with different characteristics and abilities, and that some races are better than others; a general belief about a whole group of people based only on their race
I'd say I fall under Class II. But if being more cautious around Negros and Arabs etc. because they're violent is "unfair" (which I believe it not to be), then I'd fall under Class I.
