After a discussion at the lab today, did some further reading on published social studies --- it seems like there's a replicated observation that men are more aggressive than women (although no strong consensus on whether this is primarily due to societal or biological factors).

Given this observation, does that mean that discrimination against men, for example, when considering renting housing, is justified? A little lost here... having faced housing discrimination myself, I can safely say it utterly sucks, and I don't think anyone should face it, but I also understand the importance of making sure everyone feels safe and secure. I really don't know how to resolve these two observations.
