Not so much people I respect, as people who have had a public persona I was aware of for decades, who suddenly out themselves as being a little less than tolerant, sometimes bordering on the bat-shit-crazy spectrum. Recent examples are Van Morrison and his vocal opinions on Covid measures a couple of years ago, and Scott Adams of Dilbert fame only a few days ago. I wonder sometimes how much of it is down to dotty old age and approaching dementia, and if you should forgive people for that. But it's disappointing nonetheless.
