your words:
"the question isn't necessarily about what i am going to give up, as it is impossible to give up the privilege that white skin gives me in a white supremacist society"
...ok, then whats your point? you acknowledge that we are in a 'white supremacist society,' you acknowledge that you are white. if we agree that these are both facts, then according to your own logic you are perpetuating the very system that you say you are fighting against.
