You're the one in a dream world (and a bigoted one at that) if you think that anything approaching what you're suggesting will ever happen in America, or even could happen in America.
It's flat out ignorance and sheer fantasy. Period. End of story.
The fact is that huge numbers of people, blacks, white, latinos, Protestants, Catholics, atheists, even Muslims, are peacefully coexisting all over this country.
In a nation of over 300 million souls, you choose to build your prejudices around the rare exceptions to that rule.
Shame on you.
