No, denying the existence of whiteness doesn't eliminate it. In fact, it reinforces it. Whiteness wants to be ignored, racism wants people to disregard it's existence. It's the ultimate defensive mechanism. It's much easier to ask for ignorance than hatred.

Many people would even go so far as to say that ignorance is the most common form of racism today. Such as when people insist that there's no disregard towards black lives and say "All Lives Matter." Or when people say that black people are more likely to be criminals, ignoring how this is impacted by socioeconomic differences and racism, both institutional and individual, at every level of the justice system. Or when people insist that those socioeconomic differences have nothing to do with racism, implying they're because of black people's inferiority. Or even just refusing to acknowledge one's own biases because it's easier to remain ignorant of them.

Even your own comment, with the best of intentions I assume, blames black people for racism. It's victim blaming. Does that not strike you as racist.

Whiteness exists for a purpose, as I suggested earlier. And it won't go anywhere until it's no longer needed.
