Genetics, globalization, and technological advances that have vastly improved living standards are more at fault for the "demise" of whites than simple political correctness or a few rich revenge-hungry Jews(only Quad and I have actually read a Culture of Critique, heh).
Genetics:
Black Parent + White Parent = Black Child
Indian Parent + White Parent = Indian Child
Jewish Parent + White Parent = Jewish Child(or white when it benefits them)
- However, nowadays with the rapid advancements of possible genetic alteration, it will likely be possible for prospective parents(with money) to be granted the ability to conceive a "designer" baby. In many cultures, European whites are the standards of beauty. It could be that in time that African businessmen and warlords have children with complete Scandanavian features.
Globalization:
With the advent of mass air and ship travel, the uneducated hordes with little to no hope in their home countries will risk life and limb to make it to the shores of Western nations. The generous welfare states willing to give handouts and giveaways to those masses will only serve to attract even more. It is simply much easier to escape to a different nation than it is to remain behind and attempt to fix the problems and corruption of their native lands.
Standards of Living:
There is no need to have a brood of children. The vast majority will live. Most people live within the city and literally live a life of luxury(everything available immediately at hand). In Western nations, plus Japan and Israel, the birth replacement rate (BRR) per couple is only going to continue to be on the downward trend on the south side of the 2.1 children required per couple to keep population levels stable. It is the uneducated masses from places such as Central America, SE Asian, the Middle East, and Africa that have yet to experience those same standards of living.
