> WHY they want the Nordic DNA culled?
It's because they're naturally superior in most ways. The genetically inferior brown and black people of the world want to eliminate the "competition". As Dr. Michael Savage has noted many many times, they are killing the Golden Goose as most of humanities advances have come from Nordic/White minds and hands.
If they prevail, and mediocrity is the norm, humanity will never escape Space Ship Earth and will be doomed at the bottom of a gravity well we will never escape again. We will be just another target in the cosmic shooting gallery.
