True enough. When someone is sticking a knife in your throat on a metro bus, nobody cares about the root causes.
That said, it is a discussion on the forum of potential root causes here. In summary, it isn't race, it is culture.
I think it is both race and culture—as I discussed.
Our genetic makeup has all kinds of effects on us.
The example I like to use is dangerous dog breeds.
It is absolutely true that the “culture” the dog is raised in can stop them from bad behavior almost all the time.
However under stress the dog still may “crack” and get violent if that is in their genetic makeup.
