There are some aspects of violence that can come from culture and perhaps aspects of racism or attitudes, as you mentioned in your other link. But its a vast overgeneratlization in my opinion to say that genetics is a core reason. Europeans who came to the us and owned slaves adopted ideas of racism to justify slavery that were different than what europeans chose to do. Britain has a different idea about black people as a whole than the us today, yet they have significant genetic imprint on us. The attitude of white people in certain groups today in the us (like where I'm from, the us south) who have racist attitudes about black people is different than our genetic cousins in europe. In my background in the south, people want to justify their racism so they just say "I'm not racist, I am just making observations of people's behavior". That's just an excuse for being racist.
