I would not disagree, but wouldn't that follow the demographics of the population to a big extent? If we examine other communities in other languages, what were their dispositions, who did they target or not target? Did blondes target blondes or non-blondes, etc.
In other words did it or does it show disproportionality? If it's disproportional then that indicates it's outside the global norm. The above does not mean the global norm is an acceptable norm but helps calibrate and figure out how good or bad things were or are.
