(I get that that in itself is a problem - that the issue isn't going away, evidenced by the continual posting of this articles - it just becomes a bit much for a casual internet message board)
There's a nice quote that I just read, but I forget the author: "It's easier to raise strong children than to fix broken adults". This is how we are going to fix sexism. Not by writing and reading huge personal diatribes. Not by protesting. Not by affirmative action. But by raising smart, empathetic children.
One of the strongest influences on a person is their peer group. Parents provide a model, but the peer group is where a lot of people get their core social values from. It's where you learn how to dress, how to talk, what sports to play, what music to listen to, and how to treat other people.
But to say "eh, things are getting better, don't worry about it", is completely antithetical to the idea of not writing personal stories, or protesting, or affirmative action. Things are getting better because of these things. You didn't grow up in the era of desegregation. You didn't grow up in the era of women's suffrage. These things took many, many generations to defeat, and they required long, protracted battles and getting in people's faces because most people didn't want things to get better.
Yes, we need to raise smart, empathetic children. And we need to bring them to protest rallies.
The thing I find strange is she doesn't know why the boss would deny it's a problem even after addressed by multiple people (a man, even!) with actual evidence. Basically, accepting that the problem is real would imply negative, potentially painful things about the way he lives his life, treats others, and his self image, and so he has to cling to any possible excuse to dismiss the idea so his identity isn't challenged.
It's an ego response. When threatened, the ego shapes your conscious mind's reality to protect it. It's very similar to the defense mechanism that lets creationists believe the earth is 6,000 years old and jesus rode dinosaurs. Even actual evidence to the contrary doesn't phase them. Kind of like the men in this thread who ridicule the post and ignore the actual point of it that shows a man experiencing the behavior first hand.
