So Africans have the raping gene but Scandinavians do not?

Rape is an act, not a gene. Genes can show where each ethnic groups travel however acts of rape in some countries are often unreported or under-reported for political or religious reasons. Many countries do not track the ethnicity of the attacker. Some cultures permit rape if the victim is not of the same religion but there we would delve into rather taboo topics as rarely discussed without emotion by western cultures.
