Yes, there is a grande conspiracy to kill all the white people. For example, the military takes all the best and brightest and then sends them to their deaths in foreign lands for elitist profit.
I'm not so sure about killing ALL OF THEM.
I think the illuminati uses whites as sort of an administrative body, kind of like how they used the British to build their empire. I believe some of the top illuminists are Aryan, but like the Zionists, have no problem with sacrificing their own and keeping them in bondage.
