Do black people have the power in this society to assert that claim?
What will happen if we own a business and practice discrimination towards white people, for example? When we get sued for discriminatory practices, and have to go to court, are the lawyers, judges, and jury gonna look like us, or are they gonna look like them?
If we call a white person a “cracker” is there centuries of subjugation behind that word or is it just gonna hurt their feelings? You do know that literally every language in the world has a word for black people that has negative connotations to it, right?
You can try to make your feeble case, but the facts remain.
