I do not care for my own race, the White race, per se. What I care for is a people’s capacity to produce men the likes of Socrates, Marcus Aurelius, the men of the enlightenment and American founding fathers, Darwin, Newton, Tesla etc etc.
What defines these men? Extraordinary cognitive ability and extraordinary character, traits which are not identically distributed across human populations.
I am convinced that of the current races of man, Europeans have the highest capacity to produce men of that calibre, Ashkenazi Jews and East Asians less (the Ashkenazim produce great theorists but have little ability for the practical, the reverse seems to be true for the East Asians) and most other races have little to no ability.
Putting aside my own reasons for the preservation of certain populations the fact is that racial and ethnic self-preservation is simply the instinct to preserve one's self and kin at a larger scale.
No one questions the Japanese maintaining Japan as an ethnostate of the Japanese people to this day, or the Nigerians or the Turks etc etc. It is only White Europeans who are by definition Nazis when they wish to preserve themselves as a people.
