There was a few specific things he said that rubbed me an Ultra sort of way, I can't remember much in particular.

I do remember specifically him and Hakim talking about China some 3-5ish years ago, which can be summed up by Hakim saying he was "hesistantly optimistic" about China and Paul chiming that he was "hesitantly pessimistic"--in context of whether or not China was actually socialist.

Perhaps he has changed, but people who get sucked into anti-Chinese leftist spaces tend to, in my experience, get worse with time, not better. Love to be wrong though.
