I reckon he's lying yeah. His obsession with being 'brutally honest no matter what' suggests to me that he's got a track record of lying to himself if not others.
He hid the fact that he believed in God, denied at first, then avoided, and now admits it with pride. I don't think that spells a kind of character I can trust.
I also think, as he is most well known for, that he talks out of his arse a lot of absolute codswallop which, no matter how much you break it down, turns into gobbledegook. Put him in a conversation with somebody like Stephen Fry (which happened) and he looks totally lost.
He denies climate change and all sorts of other stuff. I don't trust his words about almost anything.
Now, when he talks about issues that don't depend on his honesty, as in, philosophical points that society needs to, but may not like, to hear, free speech etc, I can often get behind a lot if not most of what he says. I think he's a potential force for good in several ways. I just wouldn't take advice from him on what to eat for dinner!
(Also, even I can tell he has a horrifically poor understanding of climate science. Like, really bad its cringeworthy)
