Personally I think it's not just caucasians.
theirs might be more visible because of their supposed cultural dominance over the world.
I don't think atrocities committed by Arabs (Isis), Mexican cartels, the Japanese in ww2, the khmers, the Tutsi genocide, the Yugoslavia war etc, etc, etc times 10 (most are undocumented) are less repulsive. Humans are messed up that's a given.
Now the question is how we Blacks can protect ourselves from being preyed upon by other races seeing how our countries are the less technologically advanced on the planet. There should be our focus.
