What does white people have to do with Taco Bell? I see mexicans, black people, asians, etc. etc. up in Taco Bell all the time.
Or because they want Taco Bell? Why even compare the two? I live in Phoenix where I can get "real" "authentic" Mexican food on just about every corner, but sometimes that weird Americanized shit like a burrito with flaming hot fritos in it or a Dorito taco shell just hits the spot.
