Yes, this is a reaching question and not well researched, but some thoughts: In countries where sex is repressed (spelling corrected) both overtly and covertly there seems to be more violence, especially against women to the point it is acceptable to kill a woman or girl who is seen is as "immoral" Middle east, India (Hindu), even Mexico (that is strictly Catholic and has strong "moral" rules). Conversely: In Europe sexual discussion is much more open, activity is accepted (modesty is expected), has a low violence to women. Japan is conservative, but depictions of and public nudity accepted in bath houses and discussion is had. Going back in US history there where times when women was persecuted for actions that include being banished. There where violent times, of course the Salem Witch trials believed to be aimed to women who where promiscuous. Today in the US it seems there is strong social restrictions on sexual behavior, and violence to women is higher than Europe but not as harsh as in other areas. Again, this is speculation.
