Steve Shives puts out excellent commentary, I wish I had the time and strength to watch all of his output. This takedown of Sam Harris is particularly well done. But it is rather long, so I recommend having it in the background to some work, like doing dishes.
I was never a fan of Sam Harris as such. I thought originally he made some good points, even about Islam, and I thought that the metaphor about us striving to reach higher grounds on an imaginary “moral landscape” was very good from didactic standpoint.
Then I learned more about Islam, and I modified my beliefs accordingly. Sam Harris AFAIK did not. I still think that the moral landscape is a good metaphor for moral progress, but that is all.
Luckily Sam Harris, unlike Dawkins outed himself as an asshole before I spent a lot of money on his books.
