See a Reuters story on Yahoo News about a Pakistani family who stoned their daughter to death on the steps of Lahore's High Court. Called an "honor killing," apparently such behavior is common in Pakistan, and widely condoned.
Her offense: she married someone of her choice, instead of her cousin as the family wished. She was at the court to testify on behalf of her husband who had been charged by the family with kidnapping.
Recently a visiting friend argued to me that all cultures are equally valid. I don't buy it. Some cultures are just ugly inhumane messes, including the one above.
