He is a tremendous intellectual that has a great amount of insight in 20th century history and how it's starting to repeat itself in the 21st century with the rise of socialism/communism and far-left (similar to Nazi and Stalinist) ideas.
I don't necessarily agree with all his analysis but he does a decent job at explaining why his ideas are valid. He does fall into the Professor trap where he tries to over explain or treat his audience as students with a significant level of prerequisite knowledge.
As far as his religiosity and ideas around it, as he has made clear, he doesn't want to expound on a topic that requires a good background knowledge, because he'd be taken out of context, hence he won't argue about those things because it takes a lot of time to properly explain a position. He also won't go into personal religious or "did Jesus really do miracles" because according to one interview, there is nothing to be gained in those debates because it depends on what you believe and how you define the words and which facts you accept. He does have a series of lectures on the Judeo-Christian values and ideas from the Bible.
All-in-all, he is honest about his views, he is open for honest discussions and when it comes to people and politics, all around brilliant in his debates with journalists and sees right through when the media is trying to entrap him into a sound bite.
