Much of JPs argument is based on evolutionary psychology. Which is contentious in itself.
He views hierarchies within that, the evolutionary context, and part of that is a male dominance hierarchy based on the threat of physical aggression, which exists at an unconscious level, even though due to the veneer of civility we have now developed , this is rarely explicit ,or carried out, even between men. But it is still there.
The idea that males used physical strength to establish dominance hierarchies, and that this still exists within their DNA at some level, is just a theory, but seems to be a plausible one.
I think what he is saying is that when debating a women those underlying aggressive instincts behind the debate are confusing to men, as it is both socially unacceptable within social norms, and has a less strong evolutionary basis for aggression to establish dominance (as the knowledge of superior strength in itself was usually sufficient in itself to suppress male/female physical conflict) so open conflict in professional settings between male and females who are equal, is incredibly new in evolutionary terms and still being figured out by the sexes.
It's interesting to consider that view point I think.
Also it does seem to chime with what we as feminists often say when observing media discourse between men and women where we note the differences in more aggressive male behaviours which are uncomfortable to view next to a more passive female. Some men are more aware of this than others. JP seems very aware.
I guess the difference is he's just saying there may be an evolutionary basis for this.
That seems likely, and socialisation emerges from an evolutionary development, which then enforces the biases which may have been there, on individuals for whom it is damaging.
I don't think it's incompatible, I just think it's a different lense.
He is definitely not one to be letting men off the hook for their behaviours. He is hard on men, and his message is individual responsibility and not the 'ah men, they can't help it because of biology' which it gets twisted into, by some MRAs who love that message, and some feminists who love to hate it, but both are failing to understand what he is actually saying.
