What he was doing was RESPONDING to the practice of racism. At best no one should mistreated white or non white, but the thing is none of this would've gotten this far if she didn't start using terms like "chicken" and "nigga" reffering to black people and then "act ignorant" like she didn't know they were black. You are a white person, you cannot be a VICTIM of racism. Non white people are subject to the system of White supremacy. You can't expect the victim to not react to racism and just keep taking abuse.
And non whites do NOT have just as much rights as white people do in the areas of (economics, education, entertainment, labor, law politics, religion, sex and war)
If you're white, you're born with benefits of epic proportions. Which means that system does still exist. Im not talking about the civil rights era and what now. This is a system thats thrives of the mistreatment of darker skin people WORLDWIDE.
