We figured out last time through a thread like this one that it's better to do something challenging as an artist rather than just trying to attack gender. Stuff like rape, domestic abuse, etc is definitely a bad idea.
As much as we're taught the opposite, men and women aren't really THAT different. Gender roles are a part of every culture and vary respectively. However, most societies around the globe are patriarchal. Obviously this means that men hold the majority of power in most social institutions. There are honest biological justifications for some of it but really it's simply about power. Men were thrust into the lead back in the day because they were the sex that could work year-round, every year. Men could farm without taking unnecessary breaks. However in order for the species to survive, women had to take time away from gathering because of child bearing. This means that for 9 months, men were the soul providers. This gave men great power. Of course being stupid apes, men assumed they were just way more awesome than women.
Anyways, I think a good topic would be a play on power. Something where women could express being in power or being powerless. I don't really care for it being an easy topic, the whole idea is to see who the best is. If one group is truly superior than the other, topic should have very little effect on the outcome.
