If barriers to women achieving goals are so prevalent in NZ that women are hampered even in intellectuals government circles, then the usual "eye rolls" from their male counterparts probably trickles all the way down to losers who live in hotels near casinos and hostels preying on young foreigners.
It's not the fact that there was a female prime minister, it's her message. Does her message trickle down to law and how men are understood through law?
For example, if a man beat a woman to death, but she was his girlfriend or wife, would the sentence be 18 months? If a man met a woman on Tinder and mistakenly believed that they were going to have sex and then she changed her mind so he accidentally murdered her. What does social culture have to believe to ensure that the sentence is greater than 18 months?
