I think sex offenders elicit emotional responses in these discussions and that the position isn't tenable at least for someone who purports to favor reintegration.
I'll pick a particularly thorny and controversial example but I think it's necessary. Imagine a member of a minority group with a background of severe violent crime spoke at a conference, he went to prison and served his sentence. Now someone attending says they don't feel save with him in the room and that the person should never hold an administrative job again. What would be the response to that?
