Cher and team seem to have decided to leave the kids' lives largely out of the story. Neither Chaz nor Elijah Blue are major characters. Although, at no point is Chaz mis-genered (nor is Elijah Blue, for that matter). And indeed, wouldn't including Chaz's story risk minimizing it? Damned if you do / don't situation--too much and it becomes Cher telling her son's story, too little and it trivializes his life and journey. Bono, Camilletti, Allman are all adults who are given a largely sympathetic presentation. They made choices to be part of this story in real life as grown men.
