Does the system of Racism (White Supremacy) exist?

I am constantly asked by Racist Suspects and the "non-white" people who worship them to "prove" that the system exists. Most of these Racist Suspects already know that it does, but behave as though it doesn't to confuse "non-white" people about it's existence. If one follows the logic, one will see that it is here. Anyway, here are a collection of videos from YouTube that I present as evidence that it does on fact exist. Below is a "playlist" of videos. They all follow behind each other, after you press play.
