If you have the average secular western mindset then you are at odds with more than half of the world population on some of the most fundamental beliefs of what normal and right and wrong is. They and many throughout history have come to completely opposite world views so why is yours better and what makes your view right and theirs wrong? Why has "natural selection" created your intuition completely differently on this side of the world than on their side? There is absolutely no framework to even talk about right and wrong from a natural selection perspective but rather might makes right. Just watch a video on life on the African Savannah of predator & prey to see what that looks like.  

Natural selection gives credibility to Nazi ideology where they were living out their intuition by killing those who believed differently. If you lived at that time in Germany you could not say Nazi ideology was wrong because the majority believed it so that made it right according to your theory
