Yes, former sex slave should absolutely be allowed to be an ambassador to the UN. Someone who has endured an experience like sex slavery or being a child soldier will have first hand knowledge of some of the horrors and challenges faced by many across the world, that another politicin who has spent his or her life in a safe place with pplenty of food, free will and saftey wouldn't understand.
The former sex slave has all the rights to be an ambassador to the UN. It was not her will to be enslaved in such an inhuman manner, lets not judge her for things that happened to her without her consent. Giving her this golden opportunity will give hope to those who have been through the same.
Being a sex slave should not be seen as something negative about a person. Sex slaves are slaves; they are held against their will. They are victims. They did not choose to be sex slaves; they were violently forced into it. It's an awful practice, and these people should not be stigmatized for it and forced to suffer even further.
Yes, a former sex slave should be allowed to be an ambassador to the UN because he or she would have many experiences to discuss with the rest of the world. A former sex slave should not be punished for being a victim. He or she should be given many opportunities.
