Also, education is not only what you learn through books (or lack thereof) but also learning through everyday life experiences that textbooks can never teach. If you're living in a large urban area, you're more likely to have diversity and multiculturalism and be forced to interact with all sorts of people that are different than you, whereas if you live in a small town in the middle of nowhere (usually made up of whites), you're likely to very rarely or never have to interact with other kinds of people or have the opportunity to build meaningful, personal relationships with them. And that's largely how prejudice and ignorance brews. Fox News will feed you bullshit propaganda like whites are being attacked and persecuted and you'll more than likely eat it all up because you nothing better. This is also why these people hate diversity, hate the ideas of immigrants. You're likely to be religious too, so you'll go to church that's probably all-white with a preacher that may or may not enforce the bigoted views that Fox News presents.

I'm totally not trying to excuse their ignorance and bigotry, but that's usually how it happens. Education is THE key to stopping most of the ignorance out there. You have to keep them engaged, stimulated, challenged and interested otherwise they won't care if all they do in the end is go home and turn on Fox News. Only then will they want to explore what's out there in the world, how interconnected and similar we all are despite our cultural/racial/religious differences and want to keep learning to expand their knowledge and further self-improvement.
