I agree with the smoker, NRA and big oil ideas.
I really still want to see someone who is white live with a black family. FX kind of stole my idea with the show Black/White, but that was such a disaster because of the people involved that it didn't really work.
Putting a white supremisist into a primarily black neighborhood would be a good start though. It'd be like American History X. Though, sadly, his fellow haters would probably just kill him instead of believing what he had to say.
