I want to attend a diverse high-school?

I'm African American and plays games online on the computer. Currently I still attend an all black, all boy school. I haven't even spoke to a Mexican, nor a white race in my entire life (only in video games) But that doesn't compare to speaking face-to-face with one. Most blacks around me don't watch anime...don't play mmo's...or even read as much as I do. So I only ask, what do you think? Should I attend a diverse high-school, or should I think about it more.
