Interested to know what you mean by 'a world of color'. Is this a futuristic post-racial world where we all look the same in regards to skin color? If so...I don't think resistance will be exclusive to white people.

I agree that white supremacy should be attacked intellectually and by force. But 'white supremacy' is currently being very loosely (at times, comically) defined. So saying that white supremacy should be attacked doesn't have very much practical function when everyone defines it differently.
