What is the alternative? I am not calling them poor, but you are calling them deluded. And I am deluded. Basically we all believe a myth.
What is more likely is that there is an underlying reason for the PR people and others to believe it. It is the reason that should be analyzed and addressed, not the people who are the product of it.
This is starting to sound a lot like http://www.econlib.org/library/Enc/PublicChoice.html
You're making the same mistake that the PR guy made (Obviously women don't play games, therefore it's an understandable mistake). Stop doing that, would be a really good start.
secondly why do you keep saying that acting based on previously established patterns in one's life is a mistake?
how do you know I'm not a nobel prize winning sociologist, and that you are the one making the mistake
"Those poor PR people, how were they supposed to know that a chick plays video games?"
