There are genetic differences between dogs just as there are with people.
With dogs there are breeds that are stronger, smarter, faster and more aggressive than others. No white man has ever run 100m under 10 seconds but many black men have. Blacks have a genetic advantage with running and jumping this is why they exceed in many sports and no one disputes this . If this is universally accepted you would foolish to dismiss other genetic differences between people also, such as average intelligence (IQ) and temperament.
According to you (and the left / media / politicians) there is no difference between a pit bull and a labrador.
Regardless, I firmly believe white europeans have a right to live with their own people as do other races and cultures. Just because we would not be living together it does not mean we have to hate each other or want to harm one another.
