There is definitely a danger of forgetting socialisation in many posts on this subject
It could be that. But if a man observed that men seem to be more inclined to use physical aggression in disputes, wouldn't we take that as a serious observation?
There is a fair bit of psychological material that suggests that women use language where men are more likely to use aggression of another kind, and we can see some similar behaviours in other social primates. And lots of people observe the same thing. Maybe that's not definitive, yes, we could be seeing what we expect to see, but then, that's a fully reversible argument. Those who want to claim that women have no more inclination to any given negative behaviour could equally be seeing what they expect to see.
Just tossing around that people are seeing what they want to is not useful, we could have said that right off to the OP with equal authority as the claim that women would be better leaders on all fronts is clearly not verifiable.
