I disagree with the premise. I see many, many celebrities who are damaged, who are loud and clear about being on the left. The media just doesn’t portray them as “damaged”.
Not a bad thing actually because they have gone through personal bad times, recovered and became responsible people. Jenner was a highly trained athlete so being a conservative was really not all that much of a surprise to me, Robert Downey, Jr, was a surprise because he was really a mess.
