Not only is it unfair it's downright RACIST. And I don't accept the BS definition that only the "majority" can be racist.
Imagine a sign in the window before the civil rights era: "Help Wanted - Negroes need not apply" - What's the UNSPOKEN message on that sign? That message is: "Jobs reserved for whites." Now take a "modern" preference - "Help Wanted - Jobs reserved for Blacks/Hispanics/Asians" What's the UNSPOKEN message? "Crackers need not apply."
It's RACISM, plain and simple.
