That is because they are the descendants of the early Darwinists, who had an incestuous relationship with the early eugenicists.
Their common goal was to rid the world of those they considered genetically inferior (sound like anyone you’ve heard of with a funny mustache?).
Their goal is to eliminate those they consider to be stupid (ever hear them refer to conservatives as anything but?), extreme (notice how all religious people are extreme), and dangerous (patriots who fight for freedom are now ‘terrorists’).
Don’t be fooled. They believe they are superior and if they get us out of their way, they can....FINALLY....create that Utopia that we keep upsetting despite their heroic efforts.
To be accurate, the early Darwinists WERE the early eugenicists, the Darwin family and their in-laws founded the eugenics movement and were its leaders for the better part of a century.
