Ultimately, it comes down to each of us opening our eyes and becoming aware of the sea of subtly sexist constructs and attitudes in which we exist, and of our own contributions to that negative state of affairs. We must rein in any casual sexism we might be guilty of, and we must do whatever we can to repair the damage by ensuring that women are enfranchised, included, and at liberty to determine their own roles.
I find it endlessly disturbing how often I hear casual sexist remarks that go uncontested, particularly when said remarks are being made by women. I couldn't agree more with Matt and commend him for articulating misogyny to an audience that is unlikely to hear about it from anyone else without immediately dismissing them.
