Feel free to criticize but do so constructively so that I may learn thanks.
He does seem to have Te/Fi; the energy (tension) never quite leaves the face and he occassionally displays sullen cheeks. Relatively steady stare (Ni) however blinking excessively (Possibly Si but more probably issues with lubrication in the eyelids; he usually doesn't wear his glasses which could either imply that they are for reading, however Hitchens would probably disregard regular glasses for a better look based on my personal understanding of his character), the scowl hints Fi + Se. Eye-centric, dominating his speech indicating Pi, also the way he composes his arguments and the way his thoughts flow, can't quite put the finger on it but I hunch NiTe or Pi-lead at least.
This one is interesting, I thought the Fi would show more in his conversations on morality (assuming I have Te/Fi right). Here he disengages eyes downwards indicating Ji (Fi) and the sullen cheeks are seen way more clearly.
Overall gives me the impression of NiTe and hopefully he hasn't been typed already because this will be awkward and I will have wasted time.
First of all, welcome to the forum! (although I might be a bit late...)
Yes, he's probably NiTe. The blinking (especially in other videos) confused me a bit but looking at photos of him, there's no doubt that he has Ni/Se. His eyes sit more at the edge of his sockets with the eyelids slightly resting on top of the eyes. There's really nothing to criticize or add as I think you put it quite well.
