As I'm sure you recognize, my post's reference to Western incidence of serial murder and paedophilia among Caucasian men as an argument for visa restrictions in China was Socratic in nature, contrasting the U.S. and British justifications for denying visas to Muslim men based on the incidence of rape in their own nation-states.

The authorities might tell us that the incidents of rape in the countries of origin of visa candidates has been seen to have a big effect and must be taken into consideration. The general quality of an immigrant should be superior to the average native of the country he wants to go to. If you source machinery from abroad you want it to be better than you can make in your own country; and the same rule should apply to people. We have some scum Anglo-Saxons and Celts in UK but we most certainly don't want to add to that scum by importing foreign scum. Well...I don't.
