Citation is needed or this is pure bullshit pulled out of your ass.
Just read the laws.
Is it true that a colored person with lower grades is given preference over other races when they apply for college?
Is it true that on govt. job applications people who are colored get points for their color only?
Doesn't the govt. force companies to hire a certain % of colored people?
Doesn't the govt. give preference on govt. contracts to companies owned by colored people?
Why do they do that?
