But we are not breeds. We are not like dogs or other animals. Now if you follow the genetic talk of some people, some cultures and races have different characteristics if you look at the genes, however, even if some Africans are good at runing doesn't mean all of them are good. And not all Europeans are good at chest. It depends on the person not on genetics.
For example, in my culture, Asatru, which is a war-like culture and is fearless in fighting, I don't think every single Asatru follower would be fearless in death. Doesn't make them less a person than anyone else. And I am sure not all Asatru people are not good in fighting, but that doesn't make them less a person.
You can't use genetics, or abilities of some people to compare a race to another. We are all people! We are all human!
