In rebuttal to preferential treatment of minorities.
An example would be: Ads for Government positions available for minorities only. Whites need not apply.
Clubs, magazines, organizations that are only open to minority races: basically including people of color, and excluding white people. All white people are of European descent, so any racism against white people can be specifically referred to as Euroracism.
"I cannot believe you would exclude me from being hired here, when I have all the credentials, just because I am white, this is Euroracism!"
