In the movie American Beauty, homophobic army guy makes a pass at straight neighbour, is rebuffed. Then filled with shame he murders the man who was the object of his desire. I thought that was too much to believe when I left the theatre but many other conversations with friends after contained remarks like “I sure that coming”.
Since then have seen the truth of that. Many people who need to communicate how much they are not something are often fighting with an inner voice and it is that fight, or at least one side of it, that we are hearing.
Trump sure tweets a lot about how ashamed other people should feel about what they do.
