Why do people like to blame diversity for the problems in America?

you must not live in america if you don't think so. you just haven't had any experiences yourself or had any friends to tell you what they have had to go through. anyone knows that's exactly what it is. i have had my own experiences where whites especially the older ones try to ruin a black persons life and act like blacks are poison. some white people do more than you think and go to further links to put someone down. i think its still because white people are so scared of everything. they were scared for us to read and better ourselves and scared of everything else and don't want anyone to be more superior than them.
