That does not mean that there is no abuse in Iran. There is.
Just so that you know, Iranian popular culture does not excuse spousal abuse. Soap operas and films do not excuse abusive men.
It is not easy to get any real information on wife beatings in Iran since most women will keep it secret. The Iranian government loves to tout the figures of abuse in the West, but they are not fooling anyone. Everyone in Iran knows that the same things happen there without the subsequent reporting.
