I have done this. People are unskilled at execution. It's not simple and it takes a bit of care, you have to display empathy that you are uncomfortable with the conclusions, and that it isn't something that you are happy or want to believe, and that if any one is ever going to provide a solution to give every one a better chance, then we will not get there with making it a crime to think this and organize around it. They just want assurance that you're not the person they read about in the history books.
