"Given the implications of saying men are naturally dominant over women I think it is you who is required to prove it tbh."
To prove what exactly? Men are naturally more aggressive than women. You don't seem to dispute that fact. I just disagree with your idea that it is because they are dominant that they are more aggressive. If you look again at the animal kingdom, the more aggressive animals will try to fight their way to the top. They get to the top because they are more aggressive and prepared to fight. The ones that do not fight will not end up as leaders. I don't think it's too much of a stretch to apply similar logic to humans and think that the ones who are prepared to fight will be the ones who come out on top.
Your initial point was:
"... I think it is natural for the dominant class to exhibit more aggression and the subjugated class to be more conciliatory. I think it has nothing to do with men/women's 'natural qualities' and everything to do with their relative positions in society."
See, I think that men were only able to achieve that 'relative position in society' because they were naturally more aggressive. Women did not fight back. Now, they do 'fight back' so we're seeing a shift. How do you think men achieved that position in society if they weren't being aggressive?
Re the nurturing point, I haven't exactly been 'labouring it'. I only mentioned it again in response to this comment of yours:
"I don't believe that women are natural nurturers anymore than I believe black people are savages."
As I said earlier, I have read papers that show that hormonal/genetic influences may make women more nurturing. I have not read any papers to suggest that black people are savages. That was why I said:
"There's a bit of a difference between saying that women may have biological influences that tends them towards nurturing and calling people 'savages' based on nothing."
I'm not sure why you think it has anything to do with the comment that we are discussing now which was:
"Perhaps males are dominant because they display more aggression as a result of their biological make up."
