Personally, I kinda hope it's soon. If we as white people have demonstrated anything over the course of human evolution, it's that we are better at warfare than the majority of the other races. There is a reason that even though there are significantly more members of other races than there are white people, most of the dominant societies that have stood the test of time have been white. The other exception is pretty much the Chinese but they are an entirely different beast and Asians fight amongst each other enough that they shouldn't be considered a substantial concern.
But truly, it may be for the benefit of everyone if we would see some honest-to-goodness attempts to cleanse whites, if for nothing else than to wake all these soy latte drinking faggots up who have been aiding and abetting the takeover of our societies and serve as a reminder that we didn't just become the dominant race on earth by virtue of our alabaster skin.
