The greatest long term obstacle to racial equality is history.
I mean, no matter if the "progressives" are successful in their bid to ethnically cleanse planet earth of Whites (through anti-White legislation, miscegenation and so on) in the present, the existence of White societies in the past will continue to shine a very unwelcomed light upon non-White societies.
Because it is a matter of fact that the more "diverse" an area or nation-state becomes, the lower its standard of living.
A majority colored America simply will never be able to achieve the progress, peace, freedom and prosperity of pre-1965 America.
How do I know this.
Well for one thing we already have such an America. It's called South America. And it is everything the social engineers tell us we should aspire towards and is our (thanks to intentionally designed policies) inevitable future.
For another thing the average national IQ of Mexico is around 88. The average IQ of blacks in America is 85.
The average IQ of Whites is 100.
Throw in various other groups who are pouring into North America and your looking at a future where the average person will have an IQ of around 90, maybe.
And as we can see RIGHT NOW is places where Whites are a minority, the future will consist of a mass of low IQ brown people ankle deep in their own waste and wallowing in perpetual crime, poverty and disease.
And above all of that will stand the image of the world before. White, clean, prosperous and beautiful, and standing in unmovable defiance for all time to the absurd lie of equality.
