Personally, i think that white supremacy is borne out of an inferiority complex to do with the size of white men's bits.
I also think that there have been numerous factors on the turning of the first world.
Firstly, a number of years ago the White residents of South Africa fled their country while being pushed out by the black people of SA, who had enough of apartheid. A great many of these people were wealthy business and land owners with great financial resources, and who held extremely racist views which were installed in them during their upbringing.
I wonder where all these people went when they left SA, and where did all their money go?
Perhaps they all grouped together and decided that they had had enough, and that what they needed to do now, is get organised and take action. As now was the time, as they already had suffered hardship due to the upheaval being forced to move from their homeland. I wonder if these people got together and put their money together and gave it all to Mr. Bannon, who then used it to fund the rise of race supremacy not only in the US but across the globe.
Steve Bannon was also the man behind Cambridge Analytica. The company that was involved in data mining facebook and engineering the past 2 US elections.
Another factor was how the Arab states held the west ransom with their oil supply. This caused major conflict between the two main territories.
Then we had 9/11, which was either caused by Al Queda as a reaction by Bin Laden, after having his millions kept in NY banks confiscated (that's the official story).
Although i would not be surprised if someone were to find evidence that Steve Bannon and perhaps some of his wealthy media mogul buddies had orchestrated the entire event, in a "Charles Mason" style Helter Skelter type of catalytic event that was designed to create a race war, or at the very least help race supremacists gain power, so they could then start to create conditions similar to that of pre-ww2.
Creating jobs out of a recession that they had created themselves, in order to make themselves look like the hero's.
In times of hardship or after many years of living day to day with no sign of hope, the people will worship any leader that puts bread on the table and gives the unemployed decent jobs, even if the jobs are preparing for war.
Obviously, the white supremacists have always been there as a minority, with the hard core ones being constantly agitating and awaiting for opportunity to seize power. I guess recessions and terrorist events are just the opportunity.
