Diversity is code for Anti-White.  When we hear how Diverse some place is it means they are replacing white people.  

Culture and Work Ethic are being treated as a Virtue of Skin Colour.  That some one who is White has it easier than some one of colour by the shear fact they have different skin.  Everything used to be based on Merit, but now if you have to many White people and/or Men you are called Racist and/or Sexist.  How dare White people and White Men in particular get the shit end of the stick for being the Majority.

Diversity Quotas is means you are supporting the idea that White people are better than everyone else since you believe that on a even playing field that non white people are not as good.
