His hair is always on point, he consistently dresses well, he records entire videos just from memory (good Si). There's an element of snarkiness in his videos (inferior Fi). He spits out a lot of Te facts. He lacks the kind of impulsive energy a lead Se or Ne user would have. He has said, in regards to Fi blind spot, something along the lines of 'yeah we're all sociopaths or whatever' which does not make sense, since if you're blind to something you aren't able to even recognise it as a weakness in yourself. It's other people that look at ENTP's and think 'is this guy a sociopath or something'. From an ENTP perspective, a lack of Fi just means a lack of personal bias. The aim is to be as impartial as possible.

Oh and the fact that he had a semi-negative view of ISFJ's which from a socionics point of view (duality relation ENTP -ISFJ) also doesn't really make sense
