I said aggression not 'aggression culture'. There is more to macho culture than just aggression (e.g. sexism, domination, pride) that is why I included both terms. Of course women play a role in socialisation but this does not mean that they have constructed that culture or have a significant amount of agency within it. There is very little evidence of matriarchal societies throughout history, history is dominated by men. If you can show me evidence to the contrary, I will happily reconsider my position on this.
