The Swiss Foreign Minister Micheline Calmy-Rey known for her stand on women's rights, covers up to meet with the Iranian regime’s representatives! When she was asked about it, she replied: "When you are a guest you respect local customs." Unfortunately people like her legitimize repression and mistreatment of women in countries ruled by oppressive regimes!
This reminds me of "The Lottery" by Shirley Jackson. Everyone should read that story to understand why it is important to stand firm against the devil. What if the local customs were cannibalism or stoning? Would she participate in those rituals as well?
