The breed lacks self esteem. Most of the Chink women are labeled SPG. Its the same phenomenon when you visit cities like Beijing or Shanghai.
Anyway nature has its method of wiping out the inferior breed. As you put it not only are SG Chinks a dying breed but so are their Commie cousins. Flat face and flat nose with crass behavior is not what natured intended.
Bo Yang, author of The Ugly Chinaman mentioned that the Chink race and civilisation are facing extinction in that book. He said that unless Chinks stop infighting & killing amongst themselves, the Chink race and civilisation are doomed to become extinct.
Mao Tse Tung killed the largest number of Chinks in China's history. He killed millions of Chinks during the Cultural Revolution. That's more than all the Chinks killed by all foreigners combined.
The Commies performed the largest number of executions of prisoners per annum in the world compared to other countries. Again, that's Chinks killing fellow Chinks to harvest their organs for sale to the highest bidders.
The Commies' 1 Child Policy is a eugenics agenda to reduce the number of Chink population.
Lots of SPG Chinks prefer to marry foreigners. Again, that's Chinks themselves wanting to dilute and reduce their own population.
Melamine milk scandal was masterminded by Chinks killing and causing illness to lots of Chink babies. Again, that's Chinks killing innocent Chink babies.
Lots of school buildings collapsed during the Sichuan earthquake. The builders, contractors, & subcontractors used cheap & substandard building materials to build those schools where lots of Chink schoolchildren died. Again, that's Chinks killing fellow Chinks.
Chinks only have themselves to blame for their own tragedies!
