that's pretty much the only explanation left when you look at the big picture, you know.
blacks chimping out is a consistent phenomenon that you can observe in literally every place on earth where blacks exist in significant numbers.
USA, south america, haiti, europe, africa - wherever you go, it's the same situation: the areas inhabited by (or even run by) blacks are complete shitholes, they constantly try to push and weasel their way into white areas as leeches and parasites, they shit up those areas with crime and disorder, and if whitey takes defensive measures to keep them out they start whining and crying about racism.
at some point you just have to fucking stop blaming everything else and acknowledge reality: the problem is THEM. they're the only constant.
