It continues to fascinate me that the men who do get it are not necessarily the ones you'd expect to get it, while the men who don't get it are often those who have nurtured a public reputation of themselves as liberal-minded free thinkers.
I think this is fascinating too, and also applies to some women, though mainly men.
It may be that if you see yourself as a liberal-minded free thinker, you don't think you need any further information to be right. You're already on board with whatever is most righteous and politically correct, so anyone trying to get to to see beyond must by trying to get you to take a step back from perfect right-on-ness. So you just don't listen.
Whereas if you don't see yourself like that, you might be more likely to let your reasoning capacity consider things and be surprised by things.
