One Tuesday a month I go to a talk put on by the local university and involving students working on their PhDs. Recently the presentation was about fentanyl deaths in prison. The student was more mature than most, in both senses of the word, and had been a prison guard before going to university. I'd turned up early and so had an older guy. The three of us got talking. The older guy suggested that fentanyl deaths in the prison was an excellent example of self-culling among some of the less sympathetic members of society. I can't remember what the former prison warder replied but he handled the quip well and was no bleeding heart. The PhD student invited questions at the end of his talk and I kept expecting that older guy to make his self-culling crack again. But he remained silent. But by then it was obvious that most of the audience for the talk were in fact out-and-out bleeding hearts. And there a few who are so intolerant and closed minded than the bleeding hearts. I'm sure the old guy wasn't the only one who wondered whether the fentanyl deaths in jail should worry society too much. It would have been an interesting discussion. But it was never going to happen. Postcript - I was foolish enough a few weeks later in the same room to question a statement that anyone who had reservations about the tactics of Extinction Rebellion activists  should be regarded as an example of "road rage culture". I should have known better.
